Rootkit Hunter
Since I only see people talking about chrootkit here is something alike(better?) nobody seems to know over here.
Rootkit scanner is scanning tool to ensure you for about 99.9% you're clean of nasty tools. This tool scans for rootkits, backdoors and local exploits by running tests like:
- MD5 hash compare
- Look for default files used by rootkits
- Wrong file permissions for binaries
- Look for suspected strings in LKM and KLD modules
- Look for hidden files
- Optional scan within plaintext and binary files
Rootkit Hunter is released as GPL licensed project and free for everyone to use.
