    Shit, lemmy world got hacked, click on that Israel will lead you to explicit picture of a bunch of naked old man sucking each other, and also pop’s up lead to porn site.

    Avoid at all cost.

      this is bad. rumour has it this is due to an admin’s json web token being leaked.

      so I would advise all admins here not to log into 3rd party web apps (mobile apps should be okay) with their admin accounts, as the web apps usually proxy your requests (hence, they have your token), and they proxy not due to nefarious purposes, but due to some problem with cors (in other words, being forced to proxy your request isn’t really their fault, and once the cors problem is fixed in the lemmy backend, they can stop doing that).

          now I’m hearing that the hack is being spread through direct messages as well.

          as this seems to be a javascript hack, all admins logged on through any web ui (even the official one) are advised to not open dm’s from unknown users.

          as mobile apps differ from browsers, and shouldn’t execute javascript directly, they should be less affected, but please take caution anyway for the time being.

          edit: it seems lemmy.blahaj.zone has been hacked too. the malicious javascript has been detected in custom emojis and community description sidebars, so admins must watch out for new users who signup and immediately start posting custom emojis or opening new communities.

              I think it is better to not open it at all (at least in the web browser, mobile apps seem to be okay, but nothing is really certain atm), as the malicious javascript seem to be connected to custom emojis and community descriptions in the sidebar (see my latest edit), so no clicking required.

      https://github.com/LemmyNet/lemmy-ui/issues/1895 has more information on mitigations, which may not be necessary if no custom emojis were added.

      it also has something for invalidating all json web tokens by changing the signing key (all users will need to re-login after doing that), which may be necessary depending on whether the tech team believes any of them (especially any of the admin’s) have been compromised (there is currently no expiry date on the tokens).

      The linked comment suggests that the entire Lemmy platform is currently vulnerable to the cookie stealing exploit that already happened to several instances.

      Now, if only we have automod that could detect code injection in markdown links and tempban offenders…
