FBI, NSA and CISA issued a joint warning<\/span><\/div>\n<\/section>\n<\/div><\/div>\n<\/div>\n

US federal cyber agencies have issued an urgent joint warning, claiming that Iranian state-backed hackers are actively breaching and tampering with industrial control systems at US water and energy providers. In an updated security advisory, the Federal Bureau of Investigation (FBI), the National Security Agency (NSA), the Cybersecurity and Infrastructure Security Agency (CISA), and the Department of Energy warned that \u201cpotentially all internet-exposed\u201d industrial control systems across critical US infrastructure could be vulnerable to attack.<\/p>\n

<\/h2>\n<\/p>\n

According to federal investigators, the Iranian-backed hackers are targeting programmable logic controllers, which are the specialised digital computers that govern physical machinery, valves, and power switches across utility networks.As per the warning, by altering display data and programming logic, the attackers have forced systems into dangerous operational states without alerting human supervisors. CISA and partner agencies are calling on all critical infrastructure operators to immediately audit their operational technology, disconnect industrial control systems from the public internet, and enforce strict multi-factor authentication.<\/p>\n

The authoring agencies urgently warn U.S. organizations of ongoing Iranian-affiliated cyber targeting of internet-connected operational technology (OT) devices, including programmable logic controllers (PLCs). These actions disrupted PLCs across several U.S. critical infrastructure sectors through malicious project file interactions and manipulation of data on human machine interface (HMI) and supervisory control and data acquisition (SCADA) displays, resulting in operational disruption and financial loss.<\/span>Last Update Description<\/span>This update adds new guidance on detecting malicious changes in reusable code modules exploited within Rockwell Automation PLC programs. It also expands scope to include observed targeting of <\/span>Schneider Electric<\/span>, Siemens, and potentially other branded\/manufactured PLCs, emphasizing the importance of restricting direct internet access and providing best practices for secure deployment.<\/span>Affected Products<\/span>Potentially all internet exposed PLCs, including Rockwell Automation\/Allen-Bradley, Schneider Electric, Siemens, and other branded\/manufactured PLCs.<\/span>Key Actions<\/span> <\/p>\n
