ClamAV is a popular tool to detect malicious software or malware. While it calls itself an antivirus engine, it probably won't encounter many viruses, as they have become rare. It is more likely to find other forms of malware like worms, backdoors, and ransomware. ClamAV can be used in a few ways, from doing an occasional scan up to scanning in batch. ClamAV does not do on-access scanning but can be combined with other tools to obtain similar functionality. ClamAV is often used to support scanning incoming emails for malicious content.

Rootkit Hunter is a small utility to find suspicious rootkit components. Other known backdoors or malicious software can also be discovered, especially if it has the goal to hide.

The tool uses different ways to hunt, like using predefined directory locations and comparing the output of system utilities. Another method is by requesting a specific output and see if this output is altered, therefore tricking rootkits to reveal themselves.

WeBaCoo could be useful for penetration tests and security assessments, to test the effectiveness of security monitoring solutions.

The chkrootkit tool consists of multiple parts that may detect the presence of rootkit parts of rootkit behavior on a system.

Some areas that are checked include:

• interface in promiscuous mode
• lastlog deletions
• wtmp deletions
• wtmpx deletions
• signs of LKM trojans
• utmp deletions

The most likely use for tools like this is backdoor a system after root permissions were gained. By planting it into the PAM stack, it allows for password sniffing.
