Description-en: 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.
.
This package is useful for network security checks, in addition to forensics
investigations.
