Threat actors are testing the waters with (not so) new attacks against ICS systems

The report reviews a confirmed intrusion into the Oldsmar, FL water treatment system where remote access (TeamViewer) was used in an attempted manipulation of chemical levels. It highlights that many ICS/SCADA environments rely on remote administration tools (VNC, RDP, TeamViewer), are often discoverable via services like Shodan, and frequently lack adequate monitoring and security controls, creating a direct risk to public safety.
