Sandbox Overview
 Execute malware in a controlled/monitored environment
 Monitors file system, registry, process and network activity
 Outputs the results in multiple formats
 Examples of Sandboxes
 Cuckoo Sandbox
 ThreatExpert
 Anubis
 CWSandbox

Why Sandbox Analysis?
To determine:
 The nature and purpose of the malware
 Interaction with the file system
 Interaction with the registry
 Interaction with the network
 To determine identifiable patterns

Custom Sandbox – sandbox.py
 Automates static, dynamic and Memory analysis using open source tools
 Written in python
 Can be run in sandbox mode or internet mode
 In sandbox mode it can simulate internet services (this is the default mode)
 Allows you to set the timeout for the malware to run (default is 60 seconds)
 Stores final reports, pcaps, desktop screeshot , and malicious artifacts for later
analysis

Sandbox.py (working)
 Takes sample as input
 Performs static analysis
 Reverts VM to clean snapshot
 Starts the VM
 Transfers the malware to VM
 Runs the monitoring tools ( to monitor process, registry, file system, network
activity)
 Executes the malware for the specified time

Sandbox.py (working contd)
 Stops the monitoring tools
 Suspends the VM
 Acquires the memory image
 Performs memory analysis using Volatility framework
 Stores the results (Final reports, destkop screenshot, pcaps and malicious
artifacts for later analysis)

Sandbox.py Report
Static analysis results:
 File type (uses magic python module)
 Cryptographic hash (md5sum – uses hashlib python module)
 VirusTotal results (python script using VirusTotal’s public api)
 Determines packers used by malware (uses yara-python)
 Determines the capabilities of the malware like IRC, P2P etc etc (uses yara-python module)

Sandbox.py report
Dynamic analysis results:
 Determines File system activity
 Determines Process activity
 Determines Registry activity
 Monitor Network activity
 Displays DNS summary
 Shows TCP conversations
 Displays HTTP requests & HTTP request tree

Sandbox.py report
Memory analysis results:
 uses Volatility advanced memory forensics framework
 displays process, hidden process in memory
 displays network connections, terminated network connections
 displays listening sockets
 determines api hooks, code injection and embedded executable in memory
 displays DLL’s loaded by the process memory
 displays services in memory
 displays the registry keys (like run registry key)
