US warns Siemens that their devices can be hacked, amid fears Iran may breach water plants

According to a cybersecurity advisory released on Wednesday, several U.S. government organizations 'warned' that hackers were trying to hack into Siemens devices used to monitor water systems and other critical infrastructure systems. Cyber experts believe that the attacks are connected to Iran. The warning coincides with a spate of cyber incidents in which local water systems have been targeted in several states over the past few weeks. According to the advisory, there is an "active" threat to all Siemens S7 Series?programmable logical controllers in multiple critical infrastructure sectors including manufacturing, energy and water and wastewater,?chemical and food and agriculture, and Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency.

The government has warned that, depending on the circumstances, compromises to these devices can lead to disruptions?of critical business processes, safety incidents or equipment damage. They could also compromise sensitive data and cause compliance violations.

Siemens did not respond immediately to a comment request. The agencies stated that the hacker's use AI to reduce the time and technical expertise required to create exploits to successfully compromise systems. CISA warned July 30 that hackers are increasingly targeting programmable controllers. This follows a warning on July 22 about Iranian hackers exploiting devices made by Siemens, Rockwell Automation, and Schneider Electric. The federal government has not formally linked Iran to recent attacks against 'local water systems. President Donald Trump stated on July 31 that Iran was not involved. He blamed Minnesota instead, which was the first state to report at least 30 cyber-attacks on water systems that occurred between July 26 and 27.
