Computer Intrusions: How a Hacker Attack on on a Water Treatment Plant Was Blocked


A computer hacker tried to add “potentially lethal levels” of sodium hydroxide – commonly known as lye – to a water treatment plant in Oldsmar, Fla., recently but was blocked by an alert employee, SecurityInfowatch.com reports.

“According to multiple published reports,” Infowatch advises, “the hacker was able to carry out the attack by compromising a remote access software program called ‘TeamViewer’ that was installed on the computer of one of the facility’s employees. Fortunately, the employee was monitoring the computer and noticed the activity of the hacker before the attack could be carried out.”

Talk about a close call! This is another example of how important it is to monitor computers in use to protect materials on them from hacker attacks. The intruder in this case “appears to have been a relative novice given the attack’s lack of sophistication.” Read on to learn how this cyber assault was blocked.
