PSA: Lemmy.world has been compromised! (Edit: Multiple Instances are down)

G59@lemmy.ml to Fediverse@lemmy.ml – 433 points –

FYI!!! In case you start getting re-directed to porn sites.

Maybe the admin got hacked?


edit: lemmy.blahaj.zone has also been hacked. beehaw.org is also down, possibly intentionally by their admins until the issue is fixed.

One of the admin accounts appears to have been compromised. The owner/other admins appear to be aware now because that account had its admin access revoked and offending posts are being removed.

Definitely opens up a big question about the security of Lemmy instances that I am sure will be discussed over the next few days.

I wouldn't assume reasons why or that it's fixed until that consensus has been more widely reached.

More time will definitely be needed. I'm glad they caught it and acted quickly enough to prevent more vandalism from occurring, but until we know how the account was compromised and what else they may have gotten in the process, it's still a situation to keep an eye on.

They added 2FA login to lemmy in one of the newer updates. Probably pretty pertinent for any admins to use it....

It’s buggy and missing some key checks to make sure it’s working when you set it up.

Real risk of locking yourself out of your account.

oh, really? maybe i'll turn mine off then.....Thanks for the heads up!

Mostly a risk on initial setup.

I’ve been waiting a bit for it to stabilize and just using huge random passwords

If you're using a password manager you'd be doing this for every site and without even having to think about it. Bitwarden is a great choice.

I like KeePass. Bitwarden currently has an nginx exposure in the Dockerfile published in their git repo (may have been fixed since a couple of days ago). That said, I used Bitwarden for many years and switched out of an abundance of paranoia, and am definitively not recommending against it. Just basically use one of the following:

  • Bitwarden
  • KeePass
  • 1password

And stay far the fuck away from LastPass

my uni is currently still recommending lastpass as of now, tho I’ve heard they might be looking for alternatives …

Let your classmates know that last pass has semi permanently damaged their trustworthiness by trying to hide a security breach, and then downplaying the severity of the breach, and that your University's security recommendations are intrinsically suspect as a result

I don't know that 1password should be on that list. The first two are free and open source. The last one is paid and proprietary.

Don't put your credentials in the hand of a company that requires you to trust them to not fuck up. Everyone thought LastPass was great until they weren't

Also I believe this was achieved through cookie stealing, which 2FA would not have helped

They really need to improve their 2fa implementation
