DEF CON 32 (2024),
Aug. 10, 2024, 2 p.m.
(240 minutes).
Email remains the #1 initial access vector for commodity malware and nation state actors. Historically, tackling email-based threats has been considered the purview of black-box vendor solutions, with defenders having limited scope (or tooling!) to swiftly and effectively respond to emerging attacker activity and novel offensive tradecraft.
In this workshop, attendees will be given detailed insight into the latest techniques used to deliver prevalent malware strains, including Pikabot and DarkGate, and will hunt through email data to identify this malicious activity, developing rules to detect and block these attacks.
Initially attendees will be introduced to the foundational technologies that enable threat hunting, detection engineering, and response in the email domain, before being given access to the email data of a fictitious company seeded with benign and real-world attack data. Throughout the day, participants will learn to hunt common phishing techniques including:
- QR codes
- Image-as-content
- Drive-by delivery via links and HTML smuggling
- Excel attachments with embedded links to SMB shares
- ISO attachments
- PDF attachments with embedded links to malware (PDF -> URL -> ZIP -> WSF)
- VIP impersonations
- BEC
Attendees will be guided through the rule creation process, utilizing free and open detection engines including Sublime and Yara, and will be introduced to the signals and email attributes that can be used to craft high-fidelity rules, including targeted user groups, sentiment analysis, sender domain age, and attachment analysis. Having completed the workshop, attendees will have a strong understanding of the tools and techniques at their disposal to defend their organizations from all manor of email threats.
