    Bad post.

    A: old news

    B: missing important context

    C: Most likely partially fabricated by law enforcement according to many experts and the tor project. They didnt execute a full timing attack because they are not capable of doing that.

    From the limited information The Tor Project has, we believe that one user of the long-retired application Ricochet was fully de-anonymized through a guard discovery attack. This was possible, at the time, because the user was using a version of the software that neither had Vanguards-lite, nor the vanguards addon, which were introduced to protect users from this type of attack. This protection exists in Ricochet-Refresh, a maintained fork of the long-retired project Ricochet, since version 3.0.12 released in June of 2022.

          I doubt it. I think OP wanted upvotes and didn’t read carefully. Something like “tor user de-anonymized via retired app” would of been more accurate.

          This is another great lesson that even the best privacy tools can’t protect a user from their own bad opsec.

          It just sucks as a lot of Lemmy users will just read the title and assume its true and then tell their friends tor is no longer safe.

      They say not given full access, so post from tor may not full picture.

      In interview daniel moßbrucker say that onion v3 was affect 2 time, so not only ricochet.

      Source for expert saying it fabricated?

      Source for government not capable of timing attack?

      Want to read up on more opinion on this.

      edit: if daniel moßbrucker trustworthy. might also fabricate story.
