Many people think that Linux is immune to the type of Autorun attacks that have plagued Windows systems with malware over the years. However, there have been many advances in the usability of Linux as a desktop OS – including the addition of features that can allow Autorun attacks.

This Shmoocon presentation by Jon Larimer from IBM X-Force starts off with a definition of autorun vulnerabilities and some examples from Windows, then jumps straight into the Linux side of things.

Larimer explains how attackers can abuse these features to gain access to a live system by using a USB flash drive. He also shows how USB as an exploitation platform can allow for easy bypass of protection mechanisms like ASLR and how these attacks can provide a level of access that other physical attack methods do not.

The talk concludes with steps that Linux vendors and end-users can take to protect systems from this threat to head off a wave of Linux Autorun malware.
