Georgia Water Utilities Hit by Cyberattacks as FBI Investigates

Federal authorities are investigating cyberattacks on water utilities across multiple states, with two confirmed incidents in Georgia (Clayton County Water Authority and Columbus Water Works). The FBI issued a nationwide alert warning that operational-technology devices used by water and wastewater facilities are being targeted, with incidents reported in at least seven states (ABC News later said up to 12). In Georgia, the intrusions affected programmable logic controllers and some pump stations, but water quality and public health were not compromised and service was restored quickly. Officials say local utilities and federal investigators are leading the response, and attribution has not yet been determined. Some counties reported no intrusions, while residents express concern about future risks.

Critical CODESYS V3 RCE Flaws Threaten Industrial PLCs Worldwide

Millions of programmable logic controllers (PLCs) used in industrial environments worldwide are vulnerable to 15 high-severity vulnerabilities in the CODESYS V3 software development kit, which could allow remote code execution (RCE) and denial of service (DoS) attacks. Over 500 device manufacturers use CODESYS V3, and Microsoft researchers discovered the flaws and reported them to CODESYS in September 2022. While security updates have been released, the nature of these devices makes patching challenging, so Microsoft has raised awareness of the risks and advises upgrading to the latest version of CODESYS V3 and disconnecting PLCs from the internet.
