Why You Should Be Searching for Linux Anti-Forensics
In this video Sandfly founder Craig Rowland discusses why it's important to hunt for anti-forensics on Linux.
Anti-forensics are techniques intruders and malware use on Linux hosts to conceal their activity. As opposed to searching for exploit signatures that have a short shelf-life, anti-forensic activity is often difficult to hide when you look for it. The irony is that unlike exploit signatures that go stale very fast, anti-forensic tactics do not change frequently and make a great way to look for signs of compromise.
Sandfly looks for a lot of anti-forensic activity because it is so good at helping zero in on attackers without needing to worry about specific attacks they may have used to gain access. This video discusses why you may want to spend more time hunting for anti-forensics vs. traditional exploit signatures.
