Just take a good backup (with the services stopped) and try to upgrade whenever an upgrade is available.
Also keep the plugins up to date if you are running any.
I'm having a problem this morning where I'm getting "Invalid credentials. Please try again." we have 2fa on all accounts.
Is anyone else having this issue? Can't log in whatsoever.
I had this problem.
Stopped the services.
Replaced the file C:\Program Files (x86)\ScreenConnect\App_Data\User.xml from the backup.
Started services.

If you cannot log in anymore you have been hacked, restore a backup and follow the above instructions.

Yes, did this. After restoring all users, we proceeded to change all passwords and reset all 2FA.
For good measure, deleted ALL extensions for now.
Also, now removed SetupWizard.aspx based on Arlecho's advice.
Not sure how best to block 91.92.255.0/24.
The username in my User.xml after the hack is 'CoHIH2rVxt' with email 'CoHIH2rVxt@poc.com' everyone else the same?
Edit: A bit of additional info, we were running ScreenConnect_23.9.7.8804_Release now updated to ScreenConnect_23.9.8.8811_Release.

If you need help blocking stuff google iptables or nftables (nftables would be prefered) or use the windows firewall if you are windows based (also enough tutorials available).
Have added some more IP ranges in the previous post.

Windows users I used the guide below to block the IP ranges in Arlecho's post above.

Simply restored my instance with a backup of yesterday, are all old users removed?

Use cloudflare, restrict access to your IP's and block all countries other than your home country
