From Clone to Cloak: Bypassing EDR with Open-Source Tooling
Logan Kroeger

Modern Endpoint Detection and Response (EDR) solutions present one of the toughest challenges for red teamers and offensive tool developers. This talk showcases a methodology used to adapt an open-source shellcode loader to bypass a modern EDR solution. Rather than showcasing a novel evasion technique destined to be signatured, the focus is on a reproducible approach to evading both static and behavioural detections.

Attendees will gain insight into the full chain of the bypass methodology:
* Identifying static signatures on disk
* Modifying loader behaviour to evade runtime detection
* Iterative testing and validation
* Applying this workflow to other public offensive tooling
