Description:
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.
