rkhunter | rootkit, backdoor, sniffer and exploit scanner | Mehr ...
Rootkit Hunter scans systems for known and unknown rootkits, backdoors, sniffers and exploits. . It checks for: - MD5 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.
