On September 5th 2013, Bruce Schneier, wrote in The Guardian:
“The NSA also attacks network devices directly: routers, switches, firewalls, etc. Most of these devices
have surveillance capabilities already built in; the trick is to surreptitiously turn them on. This is an
especially fruitful avenue of attack; routers are updated less frequently, tend not to have security software
installed on them, and are generally ignored as a vulnerability”.
“The NSA also devotes considerable resources to attacking endpoint computers. This kind of thing is done by
its TAO – Tailored Access Operations – group. TAO has a menu of exploits it can serve up against your
computer – whether you're running Windows, Mac OS, Linux, iOS, or something else – and a variety of tricks
to get them on to your computer. Your anti-virus software won't detect them, and you'd have trouble finding
them even if you knew where to look. These are hacker tools designed by hackers with an essentially
unlimited budget. What I took away from reading the Snowden documents was that if the NSA wants in to
your computer, it's in. Period”.

Preface
Preface
When the Government, Telecommunications companies and Internet Service
Providers, implant secret spying equipment in your home without your
knowledge or consent under the guise of something else, then use that
equipment to infect your computers and spy on your private network activity
(not the internet), we believe you have a right to know.
It is not possible to make these claims without actual proof and without
naming the actual companies involved.
These events coincide with the global surveillance systems recently disclosed
and they further confirm the mass scale of the surveillance and how deeply
entrenched the Governments are in our personal lives without our knowledge.
The methods we disclose are a violation of security and trust. Good
Information Security (InfoSec) dictates that when we discover such back
doors and activity, we analyze, understand, publicize and fix/patch such
security holes. Doing otherwise is morally wrong.
What is revealed here is the missing piece to the global surveillance puzzle,
that answers key InfoSec questions which include:
How do the NSA/GCHQ perform Computer Network Exploitation?
We reveal the actual methods used by the NSA/GCHQ and others that allows
them to instantly peer into your personal effects without regard for your
privacy, without your knowledge and without legal due process of law, thus
violating your Human Rights, simply because they can.
Disclosures
The risks taken when such activity is undertaken is “Being Discovered” and
the activity being “Publicly Exposed”, as well as the “Loss of Capability”.

Source of this Information
“The simple knowledge that we may be clandestinely observed in our own
homes provided the determination to find the truth, which we did.”

This information is not the result of any knowledge of classified documents or
leaks, but based on information in the public domain and our own fact finding
mission due to Forensic and Network Analysis Investigations of private SOHO
networks located in the UK.
As we detail the methods used, you will see that information was uncovered
fairly, honestly and legally and on private property using privately owned
equipment.
Our Laws
There is no law that we are aware of that grants to the UK Government the
ability to install dual use surveillance technology in millions of homes and
businesses in the UK.
Furthermore, there is no law we are aware of that further grant the UK
Government the ability to use such technology to spy on individuals, families
in their own homes on the mass scale that this system is deployed.
If there are such hidden laws, the citizens of the UK are certainly unaware of
them and should be warned that such laws exist and that such activity is
being engaged in by their own Government.
All of the evidence presented is fully reproducible.
It is our belief that this activity is NOT limited to the UK.

7

Companies
BT are directly responsible for covertly embedding secret spy equipment in
millions of homes and businesses within the UK as our evidence will
demonstrate.
BT have directly enabled Computer Network Exploitation (CNE) of all its
home and business customers.
Technical Nature of this Information
The information described here is technical, this is because, in order to
subvert technology, the attackers need to be able to fool and confuse experts
in the field and keep them busy slowing them down, but regardless, the
impact and effect can be understood by everybody.
Your main take away from this disclosure is to understand conceptually how
these attacks work, you can then put security measures in place to prevent
such attacks.

8

Credibility of this Research
We first made our discoveries in June 2013 and kept silent so that we could
research the capabilities without being detected. As more Edward Snowden
disclosures were published it became crystal clear that what we discovered is
a major component of the surveillance system.
Those who wish to discredit our evidence, feel free to do so, but do so on a
technical level, simply claiming it “it's not true” or performing some social
attack simply re-enforces it and identifies the “discreditor” as an agent of the
NSA/GCHQ or an agent of the global surveillance system.
Our evidence is based on public available UNMODIFIED firmware images.
To verify our claims using UNMODIFIED images requires connecting a USB
to serial port to the modem motherboard board which allows you to login
(admin/admin) and verify yourself. As most people will find this difficult, we
provided a link to third party MODIFIED images based on official BT release
GNU source code that allow you to telnet to the device (192.168.1.1), this
modified version includes the same backdoor. These can be found here:
http://huaweihg612hacking.wordpress.com/
and
http://hackingecibfocusv2fubirevb.wordpress.com/
The MODIFIED images have been publicly available since August, 2012, long
before the Edward Snowden disclosures.
The methods we published, allows confirmation without having to open the
device. However if you are suspicious of the MODIFIED firmware from August
2012, simply connect to the USB serial port of your own existing unmodified
modem and login to verify, either way the results will be the same.

Privacy vs Security
Loss of privacy is a breach of personal security and the legal violation of
privacy is purely a consequence of that security loss.
We've focused on the technical breach of security i.e. the Computer
Network Exploitation itself and by fixing that you can restore at least some of
your personal privacy.
This illustrates that there is no such thing as a balance between security and
privacy, you have them both or you have none.

10


Motivation
Motivation
After studying in detail the revelations by the Edward Snowden, we realized
there was a large missing part of the puzzle.
There has been little to nothing published on specifically how the attackers
technically achieve their goals. Most information published is based on
theoretical situations.
If we don't know how hackers actually achieve these security breaches, we
cannot defend against such breaches.
For example, a slide similar to the following was published, of all the slides
released, it's uninteresting and easily dismissed, as it simply describes what is
commonly known as a theoretical Man-In-The-Middle attack.

The media focus of the slide is of course the Google's Servers, and your first
thought might be, 'this is Google's problem to solve', but what if , 'Google
Server' was 'My Banks Servers', you would probably be more concerned,
because that may directly effect you.
But we thought, what if, 'Google Server', was 'Any Server, Anywhere?'
11


Our investigation led to us uncover, and understand how this attack really
works in practice, how it is implemented and the hair-raising reality of its true
nature and that is, this not just a back door, but an entire attack platform and
distributed architecture.
Terminology
To ease explanation, we are going to use standard security terms from here
on.
Attacker - GCHQ, NSA, BT Group or any combination.
The Hack – The technical method used by the attackers to illegally break into
your home network computers and phones.

12


Basic Security
Your Home Network
In order to explain how these Computer Network Exploitation attacks work,
and how this affects you personally, we must first look at the architecture of a
typical home or office network. Look familiar to you?

Most Internet connections consists of an DSL type modem and one or more
Ethernet ports attached to the modem that you connect your computers,
devices and add-on switches etc.
There are two security factors in operation here:
a) NAT based networking, meaning that your home computers are
hidden and all share a single public IP address
b) Your modem has a built-in firewall which is blocks inbound traffic. The
inherent security assumption is that data cannot pass from the inbound
DSL line to a LAN switch port without first being accepted or rejected by
the built-in firewall
13

For the technical minded, these security assumptions are further re-enforced
if the modems software is open source e.g. using Linux and that its source
code is freely and openly available as per the GNU GPL requirements.
Given that the above is the most common architecture on the Internet as it
applies to almost every home and office, everywhere, lets now revisit that first
slide, but this time, we ask one simple question:
How do the attackers get between You and Google or some other
service?
On closer inspection of the diagram you will notice that “Google Request”
and the Attacker (Log into Router) share the same router, when this slide
was released, we all assumed that this router was either Google's own router
or some upstream router, that way the attacker could intercept packets and
perform a Man-In-The-Middle (MITM) attack.
However, this would not work for every website or service on the Internet.
The attacker would need to be upstream everywhere!

So where does the attacker hide? Where is this Common
Router? again we ask:
How do the attackers get between You and Google or
some other service?
Lets examine the diagram one last time.

14


You guessed it, it's right inside your house. It's the router
supplied by your trusted Internet Service Provider (ISP).
If this is true, it means that you are being Internet wiretapped, because the
attacker has as entered your private property and unlawfully accessed your
computer equipment.
Unlike a lawful interception in which a warrant is served on the third party
(ISP), the intercept happens at the ISPs property upstream and outside your
property.
This is happening in your home or office, without your knowledge, without
your permission and you have not been served with a search warrant as is
required law.
But worse, is the fact that this architecture is designed for Cyber Attacking
in addition to passive monitoring as we will detail next.

15


The Hack
The Hack
This example is based on the UK version of what we are calling The Hack
using BT Internet services. If you are not in the UK and regardless of the
service, you should always assume that the exact same principles detailed
here are always being used against you regardless of your country or ISP
.
The Hack is based on the fact that a second secret/hidden network and
second IP address is assigned to your modem. Under normal use, you cannot
detect or see this from your LAN, but the attacker has direct access to your
modem and LAN in your house from the Internet.
How it Works
When the DSL connection is established a covert DHCP request is sent to a
secret military network owned by the U.S. Government D.O.D. You are
then part of that U.S. D.O.D. military network, this happens even before you
have been assigned your public IP address from your actual ISP
.
This spy network is hidden from the LAN/switch using firewall rules and
traffic is hidden using VLANs in the case of BT et al, it uses VLAN 301, but
other vendors modems may well use different VLANs. The original slide has a
strange number 242 with grey background, we think this represents the
VLAN number/Vendor number so BT would be 301.
This hidden network is not visible from your "Modem's Web Interface" and
not subject to your firewall rules, also not subject to any limitations as far
as the switch portion of your modem is concerned and the hidden network
also has all ports open for the attacker.
Other tools and services are permanently enabled inside the modem, which
greatly aid the attacker, such as Zebra & Ripd routing daemons, iptables
firewall, SSH remote shell server, along with a dhcp client.
These tools allow the attacker to control 100% of the modem functionality
from the Internet and in an undetectable manner. e.g., the attacker can
16

forward all your DNS requests to their private network, they can selectively
route specific protocols, ports or networks or everything to their network and
by default they do.
Although the hidden network is owned by U.S. D.O.D., it is located within the
UK as the ping time to the attacker's IP gateway is < 8ms from within the
UK.
This clearly demonstrates that the UK Government, U.S. Government, U.S.
Military and BT are co-operating together to secretly wiretap all Internet
users in their own homes (with few exceptions). The modems are provided by
BT and locked down. If you cannot confirm otherwise, you must assume that
all ISPs in the UK by policy have the same techniques deployed.
Your home network actually looks something like the following diagram. To
the right is the WHOIS record of the network our modems are automatically
connected, yours may vary.

The above hidden network is created automatically in all our test cases across
a wide range of modems.
It should be noted that even before your Point-to-Point over Ethernet (PPPOE)
request is issued, this hidden network is already fully operational. So much
so, that your LAN can be directly accessed even when you think your modem
is off-line.

17

This is an extremely complex and covert attack infrastructure and it's built
right into your modems firmware which can also be updated remotely as
required by the attacker using the built-in BTAgent.
The Hack attack is turned on by default, but is selectively turned off for
special purposes or specific dangerous customers, for example, for certain
software, firmware and hardware developers/engineers (which may include
you), so that these people don't discover The Hack.
The attacker identifies these specific “threats” and marks their Internet
connections as “NO DHCP”, such that the same dhcpc requests from their
telephone lines are ignored and while these requests are ignored, the hidden
network will not appear inside their modem and is much harder to discover.
Firmware engineers usually want to know if the modems are using Open
Source software such as Linux and Busybox, in which case they are subject to
the terms of the GNU Public License.
These engineers as well as tech savvy users may wish to put their own
software (e.g. OpenWRT) on these modems, maybe because they don't trust
their ISP but are prevented by their ISP for obscure reasons.
,
Most modem providers usually violate copyright law by not releasing the
source code and BT was no exception to this rule. Only by the threat of legal
action did they release the source code. However, BT still prevents the
modems from being updated by their customers or third parties.
BT goes to extreme lengths to prevent anyone from changing the firmware,
and those that come close are first subjected to Physical and Psychological
Barriers explained later and the few that overcome that, are subjected to a
separate NSA/GCHQ targeted Social Attack designed specifically to derail
any engineering progress made, this is also explained later. These attacks are
almost always successful.
During these attacks, BT uses all the information discovered by the engineers
to produce firmware updates that prevent anyone else using those same
techniques under the guise of security and protecting the customer and this is
performed without notice to any customers.

18

As we move to new generations of hardware, the modems are very
sophisticated and very covert, the engineers capable of even attempting to
replace the firmware become practically non-existent.
As we detail, the sole purpose of locking the modem is to prevent people
discovering that they are actually being wiretapped by BT on behalf of
NSA/GCHQ.
As a side note NSA describe Linux/Open Source as Indigenous and a SIGINT target.

NSA documents, describe this means of SIGINT collection as:

Your Real Network
Your Real Network
The following is a more realistic view of your home network and what is now
possible, given the attacker now has secret access to your home LAN.

It is now a simple matter to use other tools and methods available to the
attacker to penetrate your internal computers, this includes:
•

Steal private VPN/SSH/SSL/PGP keys

•

Steal content as required

•

Infect machines with viruses

•

Access Corporate VPNs

•

Install key loggers

•

Clean up after operations

•

Install screen loggers

•

Route traffic on demand (e.g. MITM)

•

Clone/destroy hard drives

•

Censorship and Kill Switch

•

Upload/destroy content as required

•

Passive observation

The Attacks
The Attacks
This section lists the attacks on you that are now possible by the NSA/GCHQ.
Later, we show how you can defend against these attacks and it would be wise
to implement our defenses with immediate effect.
Unlike the revaluations so far by Snowden where the attacks occur out there
somewhere on the Internet, these attacks happen in your home/office.
The attacks listed are the most obvious attacks, some are mentioned in
Edward Snowden revelations and referred to as Computer Network
Exploitation (CNE).
Internal Network Access
The attacker has direct access to your LAN and is inside your firewall.
Your modem acts as a server, it listens on lots of ports such as SSH (22) and
TELNET (23), so the attacker can just hop on to it (but you cannot).
This is possible because another hidden bridged interface exists with its own
VLAN. Firewall rules do not apply to this interface, so the attacker can see
your entire LAN and is not subject to your firewall rules because those rules
apply to the BT link (black line) not the attackers link (red lines).
When you scan your BT Public IP address from outside, you may well only see
port 161 open (BTAgent, more on this later), but when scanned from the
attackers network, all necessary ports are open and with an SSH daemon
running (even the username and password are the basic admin:admin).
Basically the attacker is inside your home network, and ironically, in most
cases, right behind your actual curtain (where the modems are usually
located).
This is the digital version of Martial Law with a Cyber Attack Soldier in every
home in the country.
The first task of the attacker is to perform a site survey and learn as much as
21

possible about all the devices attached to your network.
All your hardware can be identified by the specific MAC addresses and then
fingerprinted for specific protocols and software versions. All this cannot be
detected unless you are logged into your locked modem.
The above is just the base platform of the NSA/GCHQ from which hundreds of
types of attacks are now possible, which now include all of the following:
Man-In-The-Middle Attack
The attacker controls all outbound routes, he can easily perform an HTTPS
Man-In-The-Middle attack by forwarding specific traffic for port 443 or
destination network to a dedicated MITM network which he controls (as per
previous slides).
The only thing required is a valid SSL certificates + keys for a specific domain
(which he already has, see below), The attacker is between you and any
site you visit or any service you use (not just websites). e.g. Skype, VOIP SSH
,
etc.
The attacker simply creates a static route or more easily publishes a Routing
Information Protocol Request (RIP) request to the Zebra daemon running in
the router for the target network address and your traffic for that network
will then be routed to the attackers network undetectable by you.
The attacker can then use asymmetric routing and upon examination of the
requests he can filter specific requests he is interested in and respond to
those, but let the target website server or service respond to everything else.
The key here, is, traffic from the target website back to the user does not
then have to go via the attackers hidden network, it can go directly back to
users public IP (which would be logged by the ISP).
MITM can be on any port or protocol not just HTTPS (443), for example your
SSH connections, all UDP or GRE, PPTP IPSec etc. or any combination of
,
anything.

22

All SSL Certificates Compromised in Real-Time
The security of Public Key Infrastructure (PKI) is based primarily on the
security of the owners private keys. These private keys are not necessarily
required in order to perform a MITM attack.
All that is required is an actual duplicate signed certificate using NSA/GCHQ
own private keys. The MITM attack can be as simple as running a transparent
proxy and you will always see a valid certificate but unable to detect the
attack.
At the point of the proxy all your traffic is decrypted in real-time, at which
point targeted packet injection can occur or simply monitored.
It makes perfect sense that the trusted Certificate Authority (CA) actually
make a second duplicate SSL certificate with a separate set NSA provided
private keys, as the CA never sees the real certificate owners private keys.
When you send your Certificate Signing Request (CSR) and order your SSL
Certificate, a duplicate signed certificate is then automatically sent to the
NSA and stored in their “CES Paring database” as per Snowden releases.
We must therefore assume that NSA/GCHQ already have a duplicate of every
PKI certificate+key (key different from yours).
This means as soon as you revoke or renew your certificate, the NSA is ready
and waiting again, allowing them to do real-time decryption on almost any
site anywhere across any protocol that uses PKI.

23

Theft of Private Keys
Home networks are usually very insecure, mainly because only you or family
use them, your guard is down and your SSH, VPN, PGP SSL keys are all
,
vulnerable to theft by the attacker and his available methods.
The Hack is the key mechanism that enables these thefts.
As an example of the above, if you use the modems built-in VPN feature, you
usually add your certificate and private key to the modem or generate them
both via its web interface, at some later time, the attacker can just copy
these keys to the “CES Pairing database” via his private network, the data
collected from SIGINT can later be decrypted off-line or in real-time.
In the case of keys extracted from the modems built-in VPN, the “CES Paring
database” now contains the real key/cert pair, meaning the attacker can now
attack the VPN server environment directly when that server would have not
being exploitable otherwise.
The attacker can also mask as the genuine user by performing the server
attack from within the users modem (using the correct source IP address),
this way nothing unusual will appear in the VPNs logs. Once inside the
parameter of the VPN server the cycles repeats.
You should assume that all “Big Brand” VPNs and routers use the exact same
attack strategy and architecture with variances in the specific implementation
e.g. Big Brand supports IPSec, Little Brand supports PPTP
.
The NSA Bullrun Guide states:
“The fact that Cryptanalysis and Exploitation Services (CES) works with
NSA/CSS Commercial Solutions Center (NCSC) to leverage sensitive,
cooperative relationships with specific industry partners”.
Specific implementations may be identified by specifying Equipment
Manufacturer (Big Brand/Make/Model), Service Provider (ISP) or Target
Implementation (specific modem/router implementation).
In this disclosure, we are interested in “Target Implementation”, because in
our example case, BT has covertly implanted these devices in homes where
there is an absolute expectation of privacy, whereas the other
implementations exist within the ISP or large corporations in which you
cannot expect privacy.
It's important to remember that “Big Brands” also make small SOHO DSL and
24

cable modems.
Further evidence of the mass global distribution of this technology to at least
the 14 Eyes: USA, GBR, CAN, AUS, NZL, FRA, DEU, DNK, NLD, NOR, ESP
,
ITA, BEL, SWE and almost certainly many more countries:
Quote from GCHQ regarding their ability to steal your private keys:
It is imperative to protect the fact that GCHQ, NSA and their Sigint
partners have capabilities against specific network security technologies
as well as the number and scope of successes. These capabilities are
among the Sigint community’s most fragile, and the inadvertent
disclosure of the simple “fact of” could alert the adversary and result in
immediate loss of the capability.
Consequently, any admission of “fact of” a capability to defeat encryption
used in specific network communication technologies or disclosure of
details relating to that capability must be protected by the BULLRUN
COI and restricted to those specifically indoctrinated for BULLRUN.
The various types of security covered by BULLRUN include, but are not
limited to, TLS/SSL, https (e.g. webmail), SSH, encrypted chat, VPNs
and encrypted VOIP
.
And
Reports derived from BULLRUN material shall not reveal (or imply) that
the source data was decrypted. The network communication technology
that carried the communication should not be revealed.
From the NSA:

25

The Kill Switch
Actual capabilities uncovered here include the actual ability to apply physical
censorship on the Internet by governments directed at individuals, groups,
companies, entire countries or the majority of the users of the Internet at
once (given a coordinated government agreement). This is something that can
be turned on globally within minutes.
This “kill switch” is only a small portion of the total capabilities available that
are in place right now. Essentially, any operation that can be applied using a
single firewall or RIP router, can be applied to every customer at once.
Uploading/Download Content
The attacker can upload or download content via either your public ISPs
network or via his private hidden network. The differences is that your ISP
could confirm or deny from their logs the user did or did not upload/download
content from/to a particular source.
In other words, the possibilities and ability to frame someone cannot ever be
overlooked.
When the attackers steal content, that information always travels via the
private network.
Hacking in to a VOIP/Video Conferences in Real-Time
As an example, it's a trivial matter for the attacker to route specific traffic for
specific media protocol such as VOIP (SIP/H.323/RTSP) etc. to his network in
real-time these protocols are usually not encrypted so no key theft is required.
In the case of Skype, it's no stretch of the imagination to assume that
Microsoft handed over the keys on day one.
Those they do not redirect in real-time as we know, will be collected via
upstream SIGINT.

26

Tor User/Content Discovery
Users of the Tor network can easily be discovered by LAN packet
fingerprinting, but also by those who download the Tor client. The attacker
can stain packets leaving your network and before entering the Tor network,
making traffic analysis much easier than was previously known.
All Tor traffic can be redirected to a dedicated private Tor network
controlled by the attacker, in this way the attacker controls ALL Tor nodes
and so can see everything you do from end-to-end.
This is not something the Tor project can fix, it can only be fixed by the user
following our methods.
Tor hidden services should drop all traffic from un-trusted Tor nodes, this way
clients running in the simulated Tor network will fail to connect to their
destination.
Encrypted Content
The attacker is in your network and has all the tools necessary (such as
operating system back doors) or zero day vulnerabilities to hack into your
computers and steal your VPN, PGP SSH keys as well as any other keys they
,
desire. Also, content that is encrypted can be captured before encryption via
any number of methods when the attacker is already inside your network.
Covert International Traffic Routing
The attacker can secretly route your traffic to the U.S. without your
permission, consent or knowledge thus by passing any European data
protection or privacy laws.
Activists
We have seen many activist groups, protest organizers identified and silenced
over the few years, we believe this is the primary method used to capture
activists. Knowing the victims ISP would indicate which ISPs are involved.
Destroy Systems
Released documents state that the U.S. Cyber Command have the ability to
disable or completely destroy an adversaries network and systems, the first
step to this would be to penetrate the adversaries network firewall making
secondary steps much easier.

27

Censorship
The attacker has control of the hidden firewall, it is easy for the attacker to
simply block traffic based on specific ports or based on destination address or
network route, for example, the government can block port 8333 at source
and therefore block all Bitcoin transactions.
A coordinated attack on the Bitcoin network is possible by blocking ports of
Minors around the world. Reducing the hash rate and blocking transactions.
Mobile WIFI Attacks
Mobile devices phones/tablets etc, are as easily accessible once they connect
to your WIFI network which is, from the attackers perspective, just another
node on the your LAN that the attacker can abuse.
The level of sophistication or advanced encryption in use by your WIFI is no
defense because the attacker has gained a trusted position in your network.
All MAC addresses gathered from your LAN are stored in the XKEYSCORE
database so they can be used to identity specific devices and specific
locations, allowing the attacker to track you without the aid of GPS or where
no GPS signal exists.
Document Tracking
Microsoft embeds the physical MAC addresses of the computer inside
documents it creates. This allows the source of a document to be identified
easily. The following is from the XKEYSCORE PowerPoint.

The Mobile Hack
2G/3G/4G Mobile Attacks
Given the NSA/GCHQ plan to spy on “any phone, anywhere, any time”.
The Hack detailed in this document is a carrier independent method to
achieve that goal that works very well. The attacker will almost certainly reuse the same strategy for all Mobile phones or wireless broadband devices.
Your mobile phone (2G/3G/4G) is almost certainly subject to this same attack
architecture because from the attackers perspective, his side of the
infrastructure would remain the same regardless of device being attacked.
A mobile phone these days is simply a wireless broadband modem + phone,
so any encrypted messaging system for example can be captured before
encryption. Therefore mobile phones are subject to all the same and many
more attacks as per The Hack.
This would mean that mobile phone makers may well be in collusion with the
NSA/GCHQ because they would need to implement the equivalent routing
and firewall ability in each mobile phone as part of the OS if it was to remain
hidden.
The mobile phone version of The Hack is also much more difficult to detect
than the broadband version. Mobile phones make more use of IPv6 and the
overall complexity of IPv6 means that even experts may not know what they
are looking at in the routing tables even if they could see them. Carriers often
have multiple IPs for different services they provide.
Even top-up mobile phones without any credit can be accessed, for example,
the mobiles phones top-up services are always available and their DNS
servers are always accessible regardless of your top-credit state.
Modern kernels use multiple routing tables (e.g. ip rule show) for policy based
routing, so again unless you confirm who owns a specific IP6 range, it will be
difficult to spot, especially as firmware hackers are not even looking for such
back doors. Maybe now they will.
We do not provide defense methods for Mobile Phones at this time.

Basic Defense
Basic Defense
Knowing how you are being attacked is half the battle, but in this case, due to
the attackers abuse of a privileged position and the fact that the attacker is
your own government and its foreign partners, defense is much more difficult,
compared to a common virus, worms or hackers.
One of the best defenses is to take Legal action against BT or your ISP
.
If you are serious about your privacy, don't expect any help from your
attackers (as attackers never help their victims). You must ensure your own
privacy. Before we explain practical defenses, here are some good tips.
Secure your end-points
• Never ever trust ISP supplied equipment (e.g. router, firewall, STBs),
always consider such devices as hostile and position them in your
network architecture accordingly i.e. in the Militarized Zone (MZ)
• Do not use any built-in features of ISP equipment (e.g. Firewalls, VPNs)
• Never ever trust a device that has any closed source firmware or other
elements, regardless of the excuses the your attacker gives you
• Never trust a device that you cannot change the firmware yourself,
regardless of “big brand” names
• Disable all protocols that you don't use or don't understand, especially
TR-069 and any other Remote Management features, these are all part of
the surveillance control system (e.g. BTAgent firmware update)
• Always use a second Linux firewall which you control, that you have built
• Control all your NAT on your second Linux firewall not the ISPs supplied
router
• Make sure you control all end-points whenever possible
• Ensure that 100% of packets UDP/TCP (e.g. including DNS) are
encrypted leaving your second firewall (this is the key to end-point
security), this requires using Outbound Defense method described
later
• Always use a VPN and remote proxy that you control or trust, disable
logging altogether to protect privacy. This requires using Outbound
Defense method described later
30


Inbound Defense
Inbound Defense
This defense method against most NSA/GCHQ Inbound attacks is fairly easy
to implement and not too technical, everybody at a minimum should include
this method in their defense strategy.
The strategy will only prevent NSA/GCHQ from hacking into your home/office
LAN. It cannot prevent other direct attacks because the attacker can still
intercept and route all packets leaving your property.

A second Linux firewall device (blue) that you control and manage is
placed in front of the ISP router effectively placing the ISPs router in the
Militarized Zone (MZ) i.e. the Internet. A single cable (red) is used to link the
LAN of the ISP router to the Internet LAN port of the Linux firewall.
Block all inbound access including multicast packets from the ISP router, run
DHCP and NAT on your Linux firewall.
Your second firewall can then issue PPPOE requests via its Internet port and
create a local ppp0 device which will be its new Internet connection. All
packets leaving the firewall will now be PPPOE encapsulated.
31


Outbound Defense
Outbound Defense
This defense method should be used against all NSA/GCHQ Inbound and
Outbound attacks. This is the only sure fire method to protect Tor clients.
This defense requires that you (control/own/rent) a Server or VM elsewhere
on the Internet (far away from your ISP) and preferably in a different country.
Run a VPN such as OpenVPN between your Linux Firewall (blue) and the
your VPS server (green cloud), there, you run Squid Proxy and DNS and
block all inbound access except from your VPN. Always run your own DNS
service on your VM/Server.

32

An alternative short-term defense is to use OpenWRT router software that
you install into the modem yourself so that you can confirm no hidden
networks or IP addresses exists and that the firewall actually functions.
However, this is technically impossible for must users.
For open source router software visit https://openwrt.org/
More Defense Tips
• Isolate your WIFI from your LAN and limit by MAC address + strong
passwords alternatively, Isolate your WIFI from your LAN and leave it
open as a free hot-spot.
• If you are capable, install your own router firmware (openwrt)
• Tell your ISP you do NOT want a router with back doors or malware in it,
ask them to confirm in writing that back doors do not exist, this will help
you in court when suing them
• Stop using any operating systems that is known to contain back doors
• Only use Tor if you are using Outbound Defense method, otherwise you
could be using a NSA/GCHQ wonderland version of the Tor network
• It cannot be emphasized enough, never trust closed source routers
• Never use your ISP DNS servers

33


MITM Defense
MITM Defense
Until now, it was not fully understood how a MITM actually worked with
regard to how the attacker could get in the middle of any connection.
Now we know with 100% confidence that the man is not in the middle, but in
the modem and that's how any individual can be subjected to MITM attack.
We hereby rename this attack Man-In-The-Modem attack.
As an alternative defense for the future in place of the previous (admittedly
complex outbound defense), you could use TcpCrypt. You can prevent this
attack by ensuring that your client and servers are running TcpCrypt, which is
a TCP protocol extension. It works without any configuration and
automatically encrypts TCP connections if both server and client support it or
it will fall back to no encryption. It's also 100% NAT friendly.

Once installed, this works for any port not just port 80, it will also protects
HTTPS, SMTP SSH and every other service.

TCPCRYPT
TCPCRYPT
TcpCrypt is a very secure approach to many of the problems posed by the
NSA/GCHQ because its true native end-to-end encryption and does not
require a certificate authority and is free open source software.
The NSA have tried to kill this project a number of times and will continue to
do so or limit its use, you must not let that happen.

Let's get all TCP connections
Encrypted by default!

• a member of the security and intelligence services
• a Crown servant or a government contractor
But more importantly because:
• This information was discovered on private property
• As security conscious users of the internet, we identified serious
intentional security flaws which need to be fixed, and fast

Who should read this information
The intended audience is citizens of Europe, but anyone who is or could be a
victim of global surveillance systems, this includes everybody in the world
now and in the future.
Why does this document exist
When a person(s) or government takes away your inalienable rights such as
your Right to Privacy (especially in your own home), you take it back. This is
not something that can be negotiated or traded.
What about the debate, the balance?
There is no such thing as a balance between privacy and security, you either
have them both or you have none.
I'm an American, does this apply to me
The NSA would only use this technique in the U.S. if they really thought they
could go undetected. In the UK they have gone undetected until now (since
2011, as evidenced by the date of the firmware), you should assume that the
U.S. is doing the same to all Americans and you should use the defenses as
detailed herein as a precaution. We can turn off the lights ourselves.

36

Will stopping BTAgent software stop these Attacks
No. BTAgent is just misdirection. It is not required or directly used in the
attacks. It can be used to update the firmware of a target modem should the
attacker need specific functionality on the modem, but this would be
unusual. So, killing BTAgent is does not help (you should kill it anyway).
Is it possible that BT is unaware of this
No, this is their firmware, controlled by BT, publish by BT, updated by BT,
they also lock the modems.
My equipment is completely different?
The Hack is an NSA/GCHQ Global Strategy and its architecture is
independent of a specific make or model of modem or mobile phone, it is also
independent of the method transport e.g. dial-up vs. ADSL, DOCSIS, VDSL,
Cable modem etc.. It sits at the top of the stack (TCP/UDP etc), so however
you connect, it connects. Each implementation will vary and improve with
each generation.
You should only use, fully open source, firmware that is publicly verified.
I've never done anything wrong
Yes you have, you have allowed hackers to enter your home network and plant
malware that infects your computers, which may now have become part of a
zombie army with tentacles controlled by the NSA/GCHQ. This is worst than
any virus or worm you can imagine.
How can I verify this myself
Following the instructions in the following sections, you can also create
simulations off-line, but that is more technical.
I would like to donate and support your work
Thank you, please see the last page of this document for details.

37

How you can verify
The following section explains how you can confirm that your modem has the
GCHQ/NSA back door.
In these examples, we use two BT OpenReach white modems, (but more
accurately described as BT OverReach) models:
Huawei EchoLife HG612 and ECI B-FOCuS VDSL2 modem.
These two look almost identical. The HG612 is an earlier model.

The process of confirmation is slightly different for each modem.
We will show two of ways to verify the back door, the first is something
anyone can do and requires just the ping command. The second requires reflashing the firmware so you can login to the modem itself.
Claims of Huawei modems (Left) having back-doors are false, the vendor
(e.g. BT) build and install the OS for these modems. Huawei simply
provided hardware. ECI Telecom Ltd, is the provider of the second modem
(Right) – the more dangerous of the two.

38

Easy Confirmation
Step 1. Remove Power from the modem and disconnect the telephone line.
Step 2. On your PC (assumed Linux) add an IP address 192.168.1.100 i.e:
# ifconfig eth0:1 192.168.1.100 up
Step 3. Start to ping 192.168.1.1 from your PC i.e:
# ping 192.168.1.1
Step 4. Connect a network cable to LAN1
Step 5. Plug-in the power cable to the modem and wait for about 30 seconds
for the device to boot, you will then notice:
64 bytes from 192.168.1.1: icmp_seq=115 ttl=64 time=0.923 ms
You may notice up to ten responses, then it will stop.
What is happening is the internal Linux kernel boots, the start up scripts then
configure the internal and virtual interfaces and then turn on the hidden
firewall at which point the pings stop responding.
In other words, there is a short window (3-10 seconds) between when the
kernel boots and the hidden firewall kicks in.
You will not be able to detect any other signs of the hidden network without
actually logging into the modem, which is explained in the next section.

39

Hard Confirmation
Method 1: (no firmware modification required)
For this method, you need to connect a USB to serial port to the serial port
pins on the modem motherboard as detailed here:
http://hackingecibfocusv2fubirevb.wordpress.com/
If you are unable to use this method because it requires opening the modem,
please use method 2.
Method 2: (public firmware modification required)
For this method, you will need to re-flash the modem by following the
instructions in the document called hg612_unlock_instructions_v1-3.pdf
which is available from:
http://huaweihg612hacking.files.wordpress.com/2011/11/hg612_unlock_instru
ctions_v1-3.pdf
Or you can navigate to: http://huaweihg612hacking.wordpress.com/
and click “Unlocked Firmware Images for Huawei HG612” on the right
panel.
Once you have re-flashed your modem, you will be able to login to the modem
via telnet as follows.
Note: If your network is not 192.168.1.0, you will need to add the IP address
to your PC as explained previously, i.e.
#
#
#
#

ifconfig eth0:1 192.168.1.100 up
telnet 192.168.1.1, then login
Username: admin, Password: admin
then type: shell to get the BusyBox shell prompt.

Your telephone line (RJ11) cable should remain disconnected.
To prevent your devices firmware from being updated, disable the following
components, as they are not required for confirmation.
Kill the pid of the /bin/sh /BTAgent/ro/start (See UN-Hack later)
# kill pid
# killall tftpd sshd MidServer btagent

The device is now awaiting the hub/PC to issue a PPPOE discover request, at
which point you will receive your “Real Public IP”.
At this point the attacker has complete control of the modem and your LAN,
extra firewall rules are added the moment the ptm1.301 VLAN device is
enabled by the dhcpc command.

The UN-HACK
The UN-Hack
If you are able to login to your router (via serial port or LAN), there is a
defense which will prevent ALL the attacks using The Hack. This will unhack the modem and needs to be done after each reboot.
Step 1. Unplug the telephone cable and boot the Modem then login and issue
the following commands (in bold), the hash is the prompt (don't type that):
Kill the following processes:
# killall zebra ripd dnsmasq tftpd sshd MidServer
Kill the pids of the /bin/sh /BTAgent/ro/start:
# kill 766
Now, Kill all of the BTAgent processes:
# killall btagent
Unmount the BTAgent partition:
# umount /usr/BTAgent
Remove the attackers VLAN 301:
# vconfig rem ptm1.301
Kill the rogue dhcpc process with force (-9) or it will re-spawn
# killall -9 dhcpc
Remove all hidden firewall rules
# iptables -F -t mangle
# iptables -F -t nat
# iptables -F
Step 2. Plugin the telephone cable and the DSL will connect to BT (without
the NSA/GCHQ listening).
Step 3. Now start your PPPOE session from your second Linux firewall
machine as per the instructions for Inbound Defense and Outbound
Defense as applicable and Enjoy your privacy.

Special AgentBT
Special AgentBT
This “special“ software installed on all modems provided by BT called
BTAgent.
This software listens on port 161, which is the IANA assigned port for Simple
Network Management Protocol (SNMP), anyone looking at this process would
automatically assume this to be the case. SNMP type programs are often
referred to as SNMP Agents.
The primary purpose of BTAgent is unpublished, but a version has been
partially reverse engineered and the software does download firmware and
update the modems flash.
BT responses to queries about their BTAgent is to claim that they need to
“remotely manage modems for security purposes”.
User concerns with BTAgent:
1. It's closed source
2. Users cannot turn it of
3. The secretive nature and responses from BT
4. Users cannot upgrade the firmware using BTAgent
5. Port 161 is open to the public internet
The second (special) purpose of the BTAgent is purely reverse reverse
psychology and designed to keep you wondering about it, to cause you to
waste your time reverse engineering it, when it may well be what it says on
the tin and while your thinking about BTAgent you're not thinking about the
other network interfaces such as ptm1.301 and the dhcpc requests which all
look innocent but actually perform the dirty deeds right in the open.
When you reverse engineer BTAgent and publish your results, this allows the
NSA/GCHQ to target you for other type of attacks.
We should remember, that with a single Firmware update from BTAgent, it
could morph itself and into what we originally feared!

Psychological and
Physical Barriers
Barriers
The NSA/GCHQ will do anything and everything to stop the The Hack being
discovered. The first step is to deal with the majority of users and prevent
them from even thinking about opening it up or even touching the modem.
Some of the suggestions listed here may seem extreme, but the less interest
created in this box, the less attention it receives from consumers.
1. It's a white box, psychologically it's not a “black box” so it should be safe
2. It comes in a plain brown cardboard box, which contain no words or
graphics whatsoever, with a single white bar-code label with make/model
of the modem
3. The BT engineer personally carries and installs it in your home, while
other components such as BT Home Hub, the more expensive component
are sent through the postal system. BT cannot leave this shiny white
modem hanging around for a week while they allocate your connection,
you may try to open it or do research about it online, and they want to
know who is researching it
4. The telephone socket (RJ11) is designed such that when you plug in the
telephone cable, it becomes very difficult to remove it, much more so
than a standard telephone RJ11. Its not just a case of pinching the lever,
you have to pinch and push further in, then remove. This is subtle, but it
will prevent a lot of people from even attempting to disconnect the
telephone cable, just in case they break it
5. The older model was easy to open, just a few screws, the newer models
is almost impossible to open because it is clip locked closed, meaning
that you will damage it if you attempt to open it
6. Red Warning Sticker on the back – “Don't cover Air Holes”, wise but
scary
7. The only documentation is a single piece of white paper detailing how it
should be mounted, there is no instructions about which cables go
where, this is designed never to be touched
8. All internal serial port headers are removed so, you can easily hack it
9. The modem is plain white and square, extremely uninteresting, boring,
“Nothing to see here, move along”,
All of this subtle “Anti-Marketing” for the most advanced BT product?

Social Attacks on
Engineers
Social Attacks on Engineers
Having discovered the attack architecture and disabled it, we decided to visit
some forums online, we were interested to see if anyone, anywhere is close
to uncovering The Hack and how the NSA/GCHQ react to such issues.
Generally, there are engineers chatting and sharing pictures of their modems
and how they solder wires on to the (usually hidden) serial ports, the
discussions usually leads to login and gaining root access of the modem or
replacing the firmware altogether.
When engineers start to get really close, something usually extra-ordinary
happens, almost like “superman to the rescue”, someone who is highly
qualified, someone who has built up a reputation of being a ethical
hacker/security expert, introduces themselves and produces what appears to
be major break-through in gaining access to the modems.
However, because of the “ethical” element, superman instead of sharing the
method contacts BT, or BT contacts superman, directly and they agree to
allows BT to fix the flaw (e.g. giving BT a 30 days head start) after which,
superman will publish the method he used.
All things being equal, this is fair enough, but things are not all equal because
this was a complete smoke screen, played out to discourage the engineers
from further development knowing that in a few weeks “superman” will give
them access.
Many of the engineers/enthusiast waiting end-up getting caught by upgrades
of their modems firmware which then locks them out of the game.
This is a cat and mouse game, and engineers should be very wary of those
bearing gifts, their agenda is to slow you down and prevent you from making
any progress hoping you will just give up.
You can clearly see this on the BT forums as well others such as
http://www.psidoc.com, http://www.kits.co.uk/, http://http://community.bt.com,
and others. Reverse engineering is legal, legitimate and it is a great source of
innovation.

Counter-Intelligence
Counter-Intelligence
The NSA/GCHQ et al. have being watching and attacking us, it's about time
we turned the tables, started defending ourselves and also watching them.
This section is not going to detail specific techniques, but rather suggest
overall approaches, some of which we have done over a period of months.
NSA Honeypots
Now we understand the attack architecture, we can simulate the modem in a
MIPS Virtual Machine (BTAgent is not required).
We can route the NSA/GCHQ traffic to your lab and just let them hack away in
a private cloud while we log traffic including how they attempt to use their
back doors and other dirty tricks.
You will need to forward and tap VLAN 301 (in the case of BT et al) to the
virtual modem where you can analyze its traffic in real-time or offline, you
should always store whatever information you gather forever, (just like they
do).
After gathering enough evidence, you can then publicize it and take legal
action, your logs can be used in court when you sue the conspirators and coconspirators under the “Computer Misuse Act 1990” as well as other laws.

About the Authors
The authors of this document wish to remain anonymous. However we are
fully prepared to stand in a court of law and present our evidence.
We are a group of technical engineers, we are not associated with any
activists groups whatsoever. We don't have a name, but if we did it would
probably be “The Adversaries” according to NSA/GCHQ.
Our Mission
Freedom is only appreciated when lost. We are on the brink of a irreversible
totalitarian multi-government regime and even though the European
Parliament has stated that citizens should not have to defend themselves
against state sponsored Cybercrime, the fact remains that our own
Governments continue to attack us in our own homes while we sleep.
Our mission is defensive and legal. Our objectives are to expose the sources
and methods used by those that harms our personal freedoms and rights and
to provide practical information to individuals around the world allowing them
to defend themselves against such cyber attacks.
We believe this as well as future disclosures to be in the public interest.
Donations
Our ongoing work is technical, slow, tedious and expensive any donations are
very welcome. We only accept bitcoins at this time.
