REDWOOD CITY, Calif., July 27, 2026 (GLOBE NEWSWIRE) — Synack, the leader in human-validated AI pentesting and continuous security validation, today announced that three of its researchers and security professionals will speak at Black Hat USA 2026 and DEF CON 34. Their appearances include technical research on network infrastructure exploitation and browser-based session hijacking, as well as a panel discussion on the industry’s shift toward AI-assisted vulnerability submissions.
At Black Hat USA, Malcolm Stagg, a Synack Red Team Researcher who is presenting as an independent researcher for SODIUM-24, LLC, will examine how attackers can exploit assumptions embedded in commonly used network designs. At DEF CON, Gregory Disney-Leugers, a Senior Penetration Tester at Synack who is presenting as an independent researcher, will discuss a browser-in-the-middle technique targeting authenticated browser sessions. Eddie Rios, Information Security Analyst at Synack, will join representatives from YesWeHack, HackerOne, Bugcrowd, and Intigriti for a panel discussion on how AI affects submission volume, report quality and platform processes.
“Across network infrastructure, browser sessions and AI-assisted vulnerability submissions, the central question is the same: What can security teams trust?” said Angela Heindl-Schober, CMO of Synack. “These sessions show why assumptions must be tested and findings must be validated against real-world exploitability, especially as AI becomes more deeply embedded in offensive security.”
Alongside these sessions, Synack will host private meetings during Black Hat and DEF CON for security leaders interested in Sara AI Pentesting, continuous security validation and how human expertise and AI can work together to validate exploitable risk across the modern attack surface.
