HORSE PILL: A NEW TYPE OF LINUX ROOTKIT

No ratings

Presented at BlackHat US 2016 by

What if we took the underlying technical elements of Linux containers and used them for evil? The result a new kind rootkit, which is even able to infect and persist in systems with UEFI secure boot enabled, thanks to the way almost every Linux system boots. This works without a malicious kernel module and therefore works when kernel module signing is used to prevent loading of unsigned kernel modules. The infected system has a nearly invisible backdoor that can be remote controlled via a covert network channel. Hope is not lost, however! Come to the talk and see how the risk can be eliminated/mitigated. While this may poke a stick in the eye of the current state of boot security, we can fix it!
