lemmy.world and lemmy.blahaj.zone got hacked, admins in sopuli.xyz should enforce 2fa for admins and possibly disable/ look into possible injections from the community sidebar
I just enabled 2-factor authentication because of this. Script-kiddies are not gonna capture this instance!
It’s highly unlikely 2FA is enough to mitigate this kind of an attack. It’s a security vulnerability in lemmy itself, and they are stealing your access token instead of trying to log in as you.
edit: People, please, no reason to downvote admin ACKs. Just means they’ve at least read the message, after that, it’s their instance and they’ll do as they see fit.
OK.
Did Sopuli have any custom emojis enabled? Based on what I read about the hack the vulnerability was linked with those as detailed here.
If they’re stealing sessions that might not be enough. I saw some other mitigations discussed elsewhere.
Create new accounts & make them instance admin instead (they have to make a local comment to be made admin). Then remove your “browsing” accounts from admin group until patched.
