Forescout’s 2025 Threat Roundup: 84% OT Surge Signals Expanding Cyber Chaos

In 2025, attackers didn’t only target traditional areas of vulnerability; they went after those with the least defense and the most rapid change. These include new AI technologies, web applications, and operational technology (OT) for industries such as healthcare, manufacturing, energy, government, and finance.  

In fact, attacks against OT protocol rose by a whopping 84% with Modbus, Ethernet/IP, and BACnet at the forefront. IoT exploits increased to 19%, hitting cameras and video recorders the hardest, while network devices accounted for some 19% of all exploits. This is no surprise, because last year, IT, IoT, and OT saw broad expansion amid rapid infrastructure shifts.

These were some of the findings of the recent 2025 Threat Roundup by Forescout Technologies – Vedere Labs. The research aims to provide an overview of the global threat landscape and key trends that cyber defenders should be aware of in 2026 by reviewing the attack ...
