Additional information, 23AUG23:
On June 6th, 2023, the notorious Russian-affiliated ransomware group, Clop, claimed responsibility for an attack that targeted Progress Software’s MOVEit transfer tool. This corporate file-sharing solution has an extensive customer base in the United States. Organizations use MOVEit for secure file transfers; it’s essentially a more jazzed-up, professional version of popular file-sharing tools like Dropbox. In May 2023, cybercriminals at Clop uncovered a previously unknown vulnerability in MOVEit, which they began exploiting. Up to 130 organizations suffered from downstream impacts when the vulnerability in MOVEit enabled Clop hackers to gain access to their IT environment and steal sensitive data.
