There has been a massive amount of discussions going on on some of the CCleaner and Windows forums recently about a recent security breach that the company informed users about. A vulnerability was exploited by the hackers in the widely used MOVEit file transfer tool, which is used by thousands of organizations, including CCleaner, as a means to move large sets of sensitive data over the internet to obtain more information.
the hacker was able to gain access to the names and contact information of CCleaner's customers, as well as information about the products they had purchased. The software community forum claimed that one of the forum's admins responded that this was a scam email and that users should ignore it after a user inquired if CCleaner did send such emails in the software community forum.
Several people contacted CCleaner, and the company got back to them and confirmed that it sent out emails to those who were affected.
