rkhunter - 1.4.6-12 main

Rootkit Hunter scans systems for known and unknown rootkits,
backdoors, sniffers and exploits.
.
It checks for:
- SHA256 hash changes;
- files commonly created by rootkits;
- executables with anomalous file permissions;
- suspicious strings in kernel modules;
- hidden files in system directories;
and can optionally scan within files.
.
Using rkhunter alone does not guarantee that a system is not
compromised. Running additional tests, such as chkrootkit, is
recommended.
