FX: Developments in Cisco IOS Forensics

Attacks on network infrastructure are not a new field. However, the increasing default protections in common operating systems, platforms and development environments increase interest in the less protected infrastructure sector. Today, performing in-depth crash analysis or digital forensics is almost impossible on the most widely used routing platform. This talk will show new developments in this sector and how a slightly adjusted network infrastructure configuration together with new tools finally allows to separate crashed, attacked and backdoored routers from each other. We walk through the known types of backdoors and shellcodes for IOS as well as their detection and the challenges in doing so. "FX" Felix Lindner runs Recurity Labs.
