Chasing A Ghost: a PXA Stealer Story


Thursday, October 30, 2025

2:00 - 3:00 PM Eastern

60 minutes, including Q&A


Francisco Donoso, Chief Product and Technology Officer, and Bobby Venal, Principal Security Researcher, from Beazley Security, present a two-part, story-driven deep dive into the deception-rich attack chain behind a new infostealer dubbed PXA Stealer. In part one, they’ll walk through how the Beazley Security Labs, SentinelLabs, and Beazley Security’s MXDR teams detected and halted an in-progress campaign that was explicitly engineered to mislead both end users and the analysts examining it. They'll start with a fairly well-known code-loading trick to multiple layers of misdirection designed to mask intent and origin.

Part two reveals an unexpected twist uncovered during analysis: operational mistakes by the actor themselves opened a window into their infrastructure, tooling, and practices. Attendees can expect to see how gaps in the attacker’s tradecraft and operational security enabled additional insight into their operations.
