4,400+ Rockwell PLCs Exposed Online, 22 at Water Facilities in Attack Areas
Researchers found over 4,400 Rockwell Automation programmable logic controllers (PLCs) exposed to the internet, with 22 of them located in cities recently targeted by water system attacks. These unpatched or unprotected industrial controllers are critical to water treatment and other infrastructure, making them a serious security risk. The findings highlight the vulnerability of critical infrastructure to remote cyberattacks.
