[$] A free and open-source rootkit for Linux

While there are several rootkits that target Linux, they have so far not fullyembraced the open-source ethos typical of Linux software.Luckily, Matheus Alves has been working to remedythis lack by creatingan open-source rootkit called Singularity for Linux systems. Users who feeltheir computers are too secure can install the Singularity kernel module inorder to allow remote code execution, disable security features, and hide filesand processes from normal administrative tools. Despite its many features,Singularity is not currently known to be in use in the wild - instead, itprovides security researchers with a testbed to investigate new detection andevasion techniques.
