Threats Tagged 't1601'

Multiple U.S. federal agencies have issued a joint advisory about active exploitation campaigns targeting programmable logic controllers (PLCs) in critical infrastructure sectors such as government facilities, water systems, and energy. Attackers scan for internet-exposed industrial control systems and use legitimate engineering software with valid credentials to appear as authorized technicians. They manipulate controller logic and operator displays to conceal their activities. This campaign affects equipment from Rockwell Automation, Schneider Electric, and Siemens. Unlike a prior 2023 campaign, this ongoing activity has caused confirmed operational disruptions and financial losses. The exploitation leverages architectural weaknesses rather than software vulnerabilities and accesses systems through specific network ports.
