SSHazam: Hide Your C2 Inside of SSH
Summary
SSHazam is a technique that allows attackers to conceal Command and Control (C2) traffic within standard SSH tunnels. This method aims to bypass network detection systems by making malicious communications appear as legitimate SSH activity. The article details how to implement this for various C2 tools, using PowerShell as an example.
IFF Assessment
This technique is bad news for defenders as it provides a method for attackers to obfuscate their malicious C2 communications, making them harder to detect and block.
Defender Context
Defenders should be aware of techniques like SSHazam that leverage legitimate protocols for malicious purposes. Monitoring network traffic for unusual SSH patterns or data exfiltration masquerading as SSH sessions can help detect such evasion tactics. Understanding how C2 can be hidden within encrypted tunnels is crucial for improving threat detection capabilities.
