Wikipedia Leaks Some Users' Passwords

JJ Budion writes "If you've signed up for an account on Wikipedia.org, you may want to check this page to make sure you're not on there. It seems certain users with identical password hashes can find other user names with the same password, and Wikipedia (despite being alerted) has done nothing about the problem for the last year. A good (although slightly inflammatory) description of the problem can be found here. This is probably a good occasion to remember to use strong passwords (apparently only users with common passwords, like dictionary words, are affected)."

    To be clear, this isn't a case of Wikipedia "leaking" passwords or allowing some kind of exploit via technical means; this is Tim Starling deciding to specifically and literally publish a list of usernames that share the same password, ostensibly for the purpose of revealing trolls and flooders with multiple accounts.

    From the looks of a few of the lists (RickK, RíckK, RìckK, RiÄkK, RïckK, RiÄkK; Mäximus Rex, Maximus Rex, MaximusRex; JíangSlumDawg, JiangFlungDung; LlortTheehtTroll, LlörtTheehtTröll; The Two Trolls,The Fellowship of the Troll,The Return of the Troll,The Trolls of Navarone,Troll Silent, Troll Deep,The Trolling Stones, RangelaND Visa CONtroll), it would appear that some of these are indeed obvious duplicate accounts (whether or not they're "trolls" is, I imagine, beside the point).

    But it seems that he also caught a bunch of innocent folks who just happen to share the same password, not beyond the realm of comprehension for a password used for an "online" non-financial, non-critical site on a service with thousands of users. The submission makes it seem like Wikipedia knew about some kind of "exploit" and did nothing; rather, it seems like Wikipedia is content to let potential, and indeed confirmed in one case as admitted on the page, abuse of innocent users' privacy continue in the name of exposing possible (admittedly annoying) trolls. (That's my own take on the situation, anyway.)

    Interestingly, Wikimedia's (draft?) Privacy Policy says:

    Many aspects of the Wikimedia projects community interactions depend on the reputation and respect that is built up through a history of valued contributions. User passwords are the only guarantee of the integrity of a user's edit history. All users are encouraged to select strong passwords and to never share them. No one shall knowingly expose the password of another user to public release either directly or indirectly.

    It appears that, in this case, Wikimedia itself is implicitly "knowingly" releasing passwords to the public. One of the many problems with a community site for which there is no central responsible authority. Anyone who hasn't yet would do themselves well to read the summary of the issue linked in the submission.
