RECENT cyberattacks targeting water and wastewater facilities have impacted at least 12 US states, with confirmed incidents in Minnesota, Michigan, Georgia, and South Dakota. The FBI has reported malicious actors targeting Rockwell Automation's programmable logic controllers (PLCs), causing operational disruptions but no significant public safety threats. Though some states have been officially confirmed as affected, others like Wisconsin and New York have not confirmed any intrusions.
Federal officials suspect Iranian hackers may be responsible and are advising the water sector to enhance cybersecurity measures. CISA has also updated warnings about attacks on specific ICS devices.
