Tricks for the Triage of Adversarial Software
2021-08-07, 11:00–12:30, Workshops Track 1

A malware analysis and triage workshop covering quick static and dynamic analysis techniques along with common adversarial obfuscation techniques. Followed by a short malware analysis tournament challenge with gift-card prizes.


The workshop will cover techniques outlined in Malware Analysis Techniques (Published by Packt), written and delivered by myself, Dylan Barker, and the Technical Reviewer Quinten Bowen.

We'll examine ways to de-obfuscate common malicious scripts and droppers utilized in real-world attacks by threat actors such as those responsible for DarkSide ransomware and Emotet Banking Trojan threats.

Also covered will be ascertaining the capabilities and instruction flow of malware within NSA's Ghidra framework, crafting IOCs based on PE characteristics, and advanced dynamic analysis techniques including utilizing tools such as Inetsim, ProcDot, and manually unpacking malicious samples using debuggers to closely examine them without obfuscation.

The second half of the workshop will revolve around utilizing these techniques to answer questions, which will be scored on time and accuracy utilizing a CTF framework.
