An anonymous hacker has recently declared to have leaked a few hundred usernames and passwords from Dropbox accounts. A series of posts have in fact been made to Pastebin claiming to contain login credentials for hundreds of Dropbox accounts. The leak, which comes from an anonymous user taking Bitcoin donations for the full disclosure, contains accounts with email addresses starting with the letter "B". The hacker claims that more username/password pairs will be released as soon as they receive donations to their Bitcoin address. According to the hacker a total of 6,937,081 account credentials have so far been compromised.
