     1.4 +Unhide is a forensic tool to find hidden processes and TCP/UDP ports
     1.5 +by rootkits, LKMs or by another hiding technique.
     1.6 +
     1.7 +Detecting hidden processes. Implements six main techniques
     1.8 +
     1.9 +1- Compare /proc vs /bin/ps output
    1.10 +2- Compare info gathered from /bin/ps with info gathered by walking
    1.11 +   through the procfs.
    1.12 +3- Compare info gathered from /bin/ps with info gathered from
    1.13 +   syscalls (syscall scanning).
    1.14 +4- Full PIDs space occupation (PIDs bruteforcing).
    1.15 +5- Compare /bin/ps output vs /proc, procfs walking and syscall.
    1.16 +   Reverse search, verify that all threads seen by ps are also seen
    1.17 +   in the kernel.
    1.18 +6- Quick compare /proc, procfs walking and syscall vs /bin/ps output.
    1.19 +   It's about 20 times faster than tests 1, 2 and 3 but maybe give
    1.20 +   more false positives.
