I have just checked the post by Trezor and came to this board to see if this was posted or not. It's surprising how these crypto hacks continue. Even though it wasn't the Trezor but the 3rd party support center they use, still it's alarming. Trezor claims that no one was affected but approximately 66000 users' email and nicknames were leaked. This means the hacker has a list of 66000 Trezor users and he will surely try to use those emails to do something.
Even though they have regained access to their support center, the hacker still has a chance to use email spoofing and send emails to those Trezor users and try various hacking attempts like sending malware and asking them to download, or asking them to use new web portal which could be phishing and numerous more methods they may try. There are still a few percentage of people who might believe those emails and try those things.
