Hi - My name¹s Alec, I work for Facebook and am the team lead for Facebook over Tor.
Long story short: details will come out later, but we just did the same thing as everyone else: generated a bunch of keys with a fixed lead prefix ("facebook") and then went fishing looking for good ones. I feel that we got tremendous lucky. - alec On 10/31/14, 5:23 AM, "Mike Cardwell" <t...@lists.grepular.com> wrote: >https://www.facebook.com/notes/protect-the-graph/making-connections-to-fac >ebook-more-secure/1526085754298237 > >So Facebook have managed to brute force a hidden service key for: > >https://urldefense.proofpoint.com/v1/url?u=http://facebookcorewwwi.onion/& >k=ZVNjlDMF0FElm4dQtryO4A%3D%3D%0A&r=PKCvk5ihsZdnlobuFIuhTw%3D%3D%0A&m=CZ27 >H74ab0d0fF2o5LtJoybnrPSp3tV2eaCxPdBkwxU%3D%0A&s=df412954e11b3460e9e27ad5ae >8cb307233465ec461aa8ca461b66a94e457dfc > >If they have the resources to do that, what's to stop them brute >forcing a key for any other existing hidden service? > >-- >Mike Cardwell >https://urldefense.proofpoint.com/v1/url?u=https://grepular.com/&k=ZVNjlDM >F0FElm4dQtryO4A%3D%3D%0A&r=PKCvk5ihsZdnlobuFIuhTw%3D%3D%0A&m=CZ27H74ab0d0f >F2o5LtJoybnrPSp3tV2eaCxPdBkwxU%3D%0A&s=d9b3aa4ee032ade1291d78d5505c434b554 >faf83d500bf7760e23af875c29f57 >https://urldefense.proofpoint.com/v1/url?u=https://emailprivacytester.com/ >&k=ZVNjlDMF0FElm4dQtryO4A%3D%3D%0A&r=PKCvk5ihsZdnlobuFIuhTw%3D%3D%0A&m=CZ2 >7H74ab0d0fF2o5LtJoybnrPSp3tV2eaCxPdBkwxU%3D%0A&s=d21764a1dcedecaf889635ab6 >ca8300b1867a5084b7e78922ecdf0a911d9dfc4 >OpenPGP Key 35BC AF1D 3AA2 1F84 3DC3 B0CF 70A5 F512 0018 461F >XMPP OTR Key 8924 B06A 7917 AAF3 DBB1 BF1B 295C 3C78 3EF1 46B4 -- tor-talk mailing list - tor-talk@lists.torproject.org To unsubscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
