175: Bayrob
Jun 2, 2026
Summary
Liam Merku, a Symantec malware analyst, investigates BayRob, a sophisticated eBay fraud operation that used geo-fencing and complex proxy chains to hide its Romanian-based creators. After Merku infiltrated the network, he collaborated with FBI agents Stacey Whitaker and Ryan McFarlane, along with AOL’s Owen Miller, to track the criminals. Despite years of encrypted communications and moving infrastructure, a single unencrypted login slip-up by an attacker provided the breakthrough needed to identify the group and build a case for prosecution.
