I received a “New sign-in to your Plex account” email last night. The IP was one of the IPs for TorGuard VPN out of Chicago. This was not me as I was in bed at the time and no one else knows the password for my account. It appears that the encryption on your passwords may have been cracked already.
I changed my password and also removed the device from the “Authorized Devices” list.
Well, something like that was to be expected after the breach.
This is exactly why affected users were contacted and prompted to change their passwords.
It was a seven character alphanumeric mix that was non-sequential, non-repeating. Not strong, but not particularly weak. The password was used some other random, non-important places which have all been changed. Places that did not have a security breach.
