When Hacktivists Target Water Utilities: Inside a Russian-Aligned OT Attack

Russian-aligned hacktivist groups are increasingly targeting industrial control systems and OT environments—and sometimes it’s shockingly easy. In this episode, Daniel dos Santos, VP of Research at Forescout, walks through how his team used a honeypot to observe an attack against a simulated water treatment facility. We explore attacker motivations, common entry points, and what defenders must prioritize now.
