U.S. cybersecurity and intelligence agencies have issued a joint warning about potential cyberattacks targeting Siemens infrastructure systems, including hardware used to monitor and control water treatment facilities and other critical infrastructure.
The advisory, released Wednesday, highlights concerns that unidentified hackers may attempt to exploit vulnerabilities in Siemens equipment deployed across U.S. facilities. The warning follows a series of recent cyber incidents targeting local water supply systems in multiple states, which cybersecurity researchers have linked to Iranian state-sponsored actors.
Siemens did not immediately respond to requests for comment. The company’s hardware, including programmable logic controllers and industrial automation systems, is widely used in sectors such as water management, energy, and manufacturing.
The alert underscores growing concerns over the resilience of critical infrastructure against state-backed cyber threats. U.S. officials have previously warned that adversarial nations are increasingly probing industrial control systems for weaknesses that could disrupt essential services.
Cybersecurity experts have noted a rise in attacks on water utilities in recent weeks, with some incidents resulting in temporary disruptions to service. While Siemens has not confirmed any breaches, the company has previously issued guidance on securing its industrial systems against cyber threats.
