Iranian Hackers Target US Water Systems in Sophisticated Cyber Attack

US authorities are working to contain a hacking campaign by Iranian hackers targeting multiple drinking water and sewage systems across the country. A small number of water utilities have been compromised, but there has been no known impact on safe drinking water or operational systems. The hackers, affiliated with the Iranian Government's Islamic Revolutionary Guard Corps, have been targeting programmable logic controllers made by an Israeli company called Unitronics, which are commonly used in water and wastewater systems. US agencies have issued a cybersecurity advisory warning about the breach potential of these controllers if connected to the internet. The fragmented nature of the US water industry and the lack of basic cybersecurity protections in many systems exacerbate the problem.
