The Linux kernel has reached a great level of security and that’s exactly why malware creators moved away from kernel land to user land to develop their malicious software. That’s the case of ring3 (user land) rootkits made for Linux. Without touching the kernel and leveraging features of how the Linux loader works, criminals are able to create powerful remote access tools that stay deeply hidden in a Linux environment, giving zero or low chances for an administrator to detect them. This talk will explain how these rootkits works, present statistics related to infection, number of rootkits available, how they are sold in the underground market and propose solutions to shield Linux against these threats and methods for detection.
