Signatures are dead, or so we're told. It's true that many items that are shared as Indicators of Compromise (file names/paths/sizes/hashes and network IPs/domains) are no longer effective. These rigid indicators break at the first attempt at evasion. Creating resilient detections that stand up to evasion attempts by dedicated attackers and researchers is challenging, but is possible with the right tools, visibility and methodical (read iterative) approach. 

As part of FireEye's Advanced Practices Team, we are tasked with creating resilient, high-fidelity detections that run across hundreds of environments and millions of endpoints. In this talk we will share insights on our processes and approaches to detection development, including practical examples derived from real-world attacks.
