Maldet is a Linux malware detection scanner. Maldet is a useful tool for those that run a hosted environment like WHM/cPanel installations. As stated by the Maldet creators, it uses threat data from network edge IDS that are actively used in attacks to generate  an effective signature detection of php backdoors and darkmailers. The following steps will walk you through the process of installing maldet on your Linux machine.
