The FBI issues this week a Private Industry Notification (PIN) alert to warn companies about the risks of using out-of-date Windows 7 systems, poor account passwords, and desktop sharing software TeamViewer.
The alert comes after the recent attacks on the Oldsmar water treatment plant’s network where attackers tried to raise levels of sodium hydroxide, by a factor of more than 100. The investigation into the incident revealed that operators at the plant were using out-of-date Windows 7 systems and poor account passwords, and the desktop sharing software TeamViewer was used by the attackers to breach the network of the plant.
“The attempt on Friday was thwarted. The hackers remotely gained access to a software program, named TeamViewer, on the computer of an employee at the facility for the town of Oldsmar to gain control of other systems, Sheriff Bob Gualtieri said in an interview.” reported the Reuters.
