Forensic tool to find hidden processes and ports

Unhide is a forensic tool to find processes and TCP/UDP ports hidden by rootkits, Linux kernel modules or by other techniques. It includes two utilities: unhide and unhide-tcp.

unhide detects hidden processes using the following six techniques:

  * Compare /proc vs /bin/ps output
  * Compare info gathered from /bin/ps with info gathered by walking thru the
    procfs.
  * Compare info gathered from /bin/ps with info gathered from syscalls
    (syscall scanning).
  * Full PIDs space occupation (PIDs bruteforcing)
  * Reverse search, verify that all thread seen by ps are also seen by the
    kernel (/bin/ps output vs /proc, procfs walking and syscall)
  * Quick compare /proc, procfs walking and syscall vs /bin/ps output

unhide-tcp identifies TCP/UDP ports that are listening but are not listed in /bin/netstat through brute forcing of all TCP/UDP ports available.

This package can be used by rkhunter in its daily scans.
