Breaking Into Banks and Bypassing Modern Security with Greg Hatcher and John Stigerwalt

Three banks in four days isn't just a bragging right for penetration testers. It's a wake-up call showing that expensive security tools and alarm systems often fail when tested by skilled operators who understand both human behavior and technical vulnerabilities.

Greg Hatcher and John Stigerwalt, co-founders of White Knight Labs, talk about their latest physical penetration tests on financial institutions, manufacturing facilities protecting COVID-19 vaccine production, and why their new Server 2025 course had to rewrite most common Active Directory tools. They share stories of armed guards, police gun draws, poison ivy reconnaissance, and a bag of chips that saved them from serious trouble. The conversation reveals why EDR alone won't stop ransomware, how offline backups remain the exception rather than the rule, and what security controls actually work when attackers bring custom tooling.
