Since late 2023, Microsoft has observed an increase in reports of attacks focusing on internet-exposed, poorly secured operational technology (OT) devices.
Internet-exposed OT equipment in water and wastewater systems (WWS) in the US were targeted in multiple attacks over the past months by different nation-backed actors, including attacks by IRGC-affiliated “CyberAv3ngers” in November 2023, as well as pro-Russian hacktivists in early 2024. These repeated attacks against OT devices emphasize the crucial need to improve the security posture of OT devices and prevent critical systems from becoming easy targets. OT systems, which control real-world critical processes, present a significant target for cyberattacks.
