unhide - 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.
