Cyberattacks on Minnesota Water Systems Investigated as Officials Warn About Iranian Hackers
By Associated Press
AI Summary
CISA issued a public alert warning of a spike in cyberattacks targeting U.S. water systems, specifically advising operators to immediately remove PLCs and OT devices from public internet exposure. Investigations into attacks on Minnesota water systems point to Iranian threat actors, with experts citing Iran's geopolitical motivations and documented history of targeting water infrastructure — though Trump publicly contradicted intelligence agencies by blaming Minnesota. Security teams managing ICS/OT environments should treat exposed PLCs as critical attack surface requiring immediate remediation.
