Persons who have used Passwordstate’s password manager must be careful as there has been a large data leak.

Hackers placed malicious files inside the application, breaching the security of 29,000 companies and 370,000 employees using Passwordstate.

According to the dobreprogramy portal, the scale of the leak is so huge, because the malicious code planted by hackers on Click Studios’ servers was sent as part of the update. The update was automatic and the malicious code made it possible to download information about the victim’s computers along with passwords from Passwordstate application.

The data leak is serious due to the fact that Passwordstate is used by many of the largest companies in the world, according to the dobreprogramy portal, including those in the Fortune 500 ranking.
