Win-DDoS: A stealthy DDoS attack with high bandwidth

Adams explained that the Russian threat actors employ a multi-faceted approach: First, they exploit the unpatched CVE-2018-0171 vulnerability. Following a successful breach, they conduct network reconnaissance, focusing on industrial control system protocols. They also utilize sophisticated post-exploitation tools, such as custom SNMP tooling for persistence and the SYNful Knock firmware implant, to maintain covert access and evade detection for extended periods. https://lnkd.in/dRePswfM

FBI and Cisco warn: Russia-linked Static Tundra is exploiting a seven-year-old Cisco Smart Install vulnerability to pillage thousands of unpatched network devices tied to power, water, #telecom, and other sectors https://lnkd.in/e7wTNQTR #IT #OT #CriticalInfrastructure

Organizations need evidence, not promises. Keysight’s BreakingPoint QuickTest utilizes standardized NetSecOPEN methodologies that empowers security vendors and enterprises alike to validate performance and protection with confidence — ensuring critical networks are both fast and secure. #Keysight #CustomerConfidence #CyberSecurity #TestAutomation #NetworkSecurity

🔻 ZERO-DAY ALERT: Your TP-Link router could be silently hijacked RIGHT NOW. #CISA is warning of active attacks—and a NEW unpatched #vulnerability is in the wild. Hackers are chaining flaws to turn home and office routers into proxy bots for large-scale attacks on cloud platforms. ⬇️ Here’s what you MUST do immediately: 1️⃣ DISABLE CWMP/TR-069 in your router settings if not needed. 2️⃣ CHANGE default credentials—yes, still a thing! 3️⃣ UPDATE firmware—check regional availability. 4️⃣ SEGMENT your network. Isolate the router from critical systems. This isn’t just a home user issue. These compromised devices are being weaponized against corporate networks and #Microsoft 365 tenants. Monitor for abnormal DNS or outbound traffic. Are you patching your network gear as diligently as your servers?

📚 What I Learned Today – Subnetting Demystified! 🖧 Today, I finally understood how subnetting works and why we "steal" bits from the host side. 🔹 Subnetting = Dividing a network into smaller networks. 💡 Key Learnings: /24 gives you 254 usable hosts. /26 breaks that network into 4 smaller networks with 62 usable hosts each. /32 is for just one IP (often used for firewall rules). Understanding subnetting helps in: ✅ Efficient IP address allocation ✅ Better network segmentation & security ✅ Avoiding IP wastage in large networks #Networking #Subnetting #CIDR #LearningJourney #Tech #SoftwareEngineering #CloudComputing

In computing, a denial-of-service attack (DoS attack; UK: /dɒs/ doss US: /dɑːs/ daas[1]) is a cyberattack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.[2] The range of attacks varies widely, spanning from inundating a server with millions of requests to slow its performance, overwhelming a server with a substantial amount of invalid data, to submitting requests with an illegitimate IP address.[3]

𝗪𝗼𝗿𝗿𝗶𝗲𝗱 𝗮𝗯𝗼𝘂𝘁 𝗥𝗼𝗴𝘂𝗲 𝗜𝗣𝘃𝟲 𝗥𝗼𝘂𝘁𝗲𝗿𝘀 𝗼𝗻 𝘆𝗼𝘂𝗿 𝗻𝗲𝘁𝘄𝗼𝗿𝗸?  Good news! Aruba Central now consumes RA Guard telemetry and will notify network admins immediately when an RA Guard violation is detected. This means faster detection and response to unauthorized IPv6 Router Advertisements, keeping your network secure from potential attacks. This powerful feature is rolling out to production clusters within the next two weeks.

Supporting MSPs in Doing the Right Thing Many MSPs’ clients ask them to try to secure remote connectivity managing third party routers and configuring VPNs. But most off-the-shelf devices are still difficult to manage, patch, and standardise at scale. The NSA’s advice in February of this year is great, but hard to deliver without a system built for the edge. Loxada helps MSPs offer a best-practice solution without the overhead. Pre-configured, fully managed routers that keep remote access simple, secure, and compliant and with no surprises buried in the firmware.

Day 6- Port Security 🗝️ One simple misconfigured port can let an unauthorized device into your network. That’s where Port Security comes in: ✅ Limit the number of MAC addresses per port ✅ Define trusted devices using sticky MAC ✅ Choose violation actions → Protect / Restrict / Shutdown Real-world use case: • A user plugs in a mini switch under their desk → suddenly multiple devices start consuming IPs. With Port Security, that port gets shut down instantly. 🚫 🔑 It’s a lightweight but powerful defense at the edge. #Networking #Layer2 #PortSecurity #Cisco
