This week we are joined by Daniel Schwalbe, Chief Information Security Officer & Head of Investigations at DomainTools, discussing their work on "ZionSiphon OT Malware First Attempts? Psyops? Both?" Researchers at DomainTools take a closer look at ZionSiphon, a purported operational technology malware sample targeting the water sector, and find that despite its alarming appearance, it lacks many of the capabilities needed to function as a credible cyber-physical weapon.

They break down the malware's architecture, its operational shortcomings, and why it may be more of a prototype or proof of concept than a deployable threat. With heightened concern surrounding attacks on critical infrastructure amid the ongoing U.S.-Iran conflict, the research offers timely insight into separating genuine OT threats from overhyped malware.
