Packages and Binaries:
Unhide.rb is a forensics tool to find processes hidden by rootkits.
It looks for active processes in many different ways. Processes found by some means but not others are considered to be “hidden”, and are reported to the user.
Unhide.rb is a tentative of rewrite in Ruby of the original Unhide, which is written in C. While being much faster, it does not implement all the diagnostics of the original version. It is also less secure as it cannot be statically compiled.
This package can be used by rkhunter in its daily scans.
How to install:
sudo apt install unhide.rb
Scans system for hidden processes and lists any hits on stderr.
