A hacker remotely accessed the computer system controlling the Oldsmar, Florida water treatment plant and attempted to increase the sodium hydroxide (lye) level in the water supply by 111 times — from 100 parts per million to 11,100 parts per million, a level that would have caused severe chemical burns if consumed. A plant operator noticed the cursor moving and the chemical levels changing in real-time and immediately reversed the change. The attack lasted minutes. The attacker gained access through a remote desktop software program. The incident exposed the widespread use of unsecured remote access tools at water treatment facilities across the US. The hacker was never identified.
