if you has account there, maybe, it depends how good is the cryptograph used in the lemmy.world, but if they got hacked, it’s means that others intances can too, so be sure to always have a different password for every account, and this is a rule to every account in the internet(you can use good and secure password manager)
Yeah anyone not using randomly generated passwords at this point is just fucking up. I know exactly three of my passwords: the one for my email, the one for my password manager, and the one I'm likely to give out (streaming services and such). The worst anyone can do with the third is cancel my Disney+ or something, and it's really only given to my mom and sisters.
Well this was a JWT compromise, I think, but even still people use really bad passwords all the time. A salt is stored with the user record. The salt's job is to invalidate rainbow tables. If you have a collection of a million bad passwords you can check them all salted in a second or two. Obviously that'll depend on the hashing algorithm to an extent.
Yes. They got hacked. An admin account got compromised, and the hackers exploited a bug in Lemmy-UI (the web site) that let them do things like redirect users to another site that let them run Javscript. It seems to have let them collect some user tokens from accounts, and access an admin account that way.
Looks like Lemmy code has a security vulnerability, persistent XSS, that allows injection of Javascript into the sidebar and comments. That allowed the attacker to force load NSFW content even after lemmy.world admins cleaned up the first attack.
There might have also been an admin account compromise at lemmy.world involved. Time will tell if these are related.
Edit: Looks like the injected JS code also steals login tokens from your browser, so that explains the admin compromise. Probably a good idea to not visit Lemmy sites for time being (or block Javascript in your browser, which is always a good idea).
maybe?, but wihy others didn’t get hacked at the too?, maybe was social engineering, or the admin got their credentials compromised, we can’t be sure yet
Others did get hacked, or are vulnerable to it, but aren't big enough targets?
Beehaw is closed, so they would have had to have an existing account to exploit the same bug (or go through something like Kbin), and Lemmy.world is the biggest Lemmy instance.
