Attackers breached a Polish CHP plant through a Fortinet device and private APN, reaching PLCs and disrupting turbine and water treatment systems. Poland’s CERT has described a second attack on the country’s energy sector, and this one matters for a simple reason: it shows how an ordinary-looking network design can turn into a route into […]
After attacks hit 30+ Minnesota water systems, CISA urged utilities to remove internet-exposed PLCs and strengthen OT security. Between Sunday and Monday, July 26 and 27, a coordinated cyberattack hit operational technology (OT) systems at more than 30 community water utilities across the state, according to Minnesota IT Services (MNIT). “A coordinated cyberattack targeted operational technology […]
Coordinated OT cyberattacks hit 30+ Minnesota water utilities, briefly disrupting one plant. Backup procedures prevented major water service impacts. Minnesota just had its own live-fire lesson in what happens when someone targets water utilities at scale. Between Sunday and Monday, July 26 and 27, a coordinated cyberattack hit operational technology (OT) systems at more than […]

The malware combines […]
Hackers breached Venice ’s San Marco flood system, claiming control of pumps and the ability to disable defenses and flood coastal areas. The technologies that govern the physical world are the quiet infrastructure of modern life. From energy grids to water systems, from factories to flood defenses, operational technology (OT) has long had one essential […]
Censys researchers found 5,219 exposed Rockwell PLCs online, mostly in the U.S., urging defenders to secure or disconnect them. On April 7, 2026, U.S. agencies, including FBI, CISA, and NSA, warned of Iran-linked APTs exploiting internet-exposed Rockwell Automation PLCs. Threat actors are carrying out cyberattacks targeting internet-connected operational technology (OT) across multiple critical infrastructure sectors. […]
Exposed ICS devices and insecure protocols like Modbus increase risks to critical infrastructure, enabling disruption, data access, and potential sabotage. Malware targeting industrial control systems (ICS) poses a serious risk to critical infrastructure, with threats like Stuxnet, Industroyer, Triton, Havex, and BlackEnergy already demonstrating the ability to disrupt operations, cause outages, and even inflict physical […]
