A Dropbox spokesperson couldn't elaborate. Assuming the hackers do have the login information for 7 million Dropbox accounts, it's unclear how they were able to associate that information from a third-party service and apply it to Dropbox. Those third parties have become the target for hackers to obtain personal information. It's also possible for hackers to hack other sites and cross reference the login information with services like Dropbox since many people use the same logins for multiples services. Even though Dropbox's own servers weren't hacked, the service still allows third parties access. The real problem in both cases appears to be the way popular services allow users to log in. Snapchat claimed its servers weren't hacked, but the servers of a third-party app designed to save Snapchat photos were. It's a similar response to the one Snapchat had when hackers were able to obtain about 100,000 photos from the service through a third-party app. That means it's possible that there are nearly 7 million other Dropbox accounts still vulnerable. A Dropbox spokesperson told Business Insider that Dropbox consistently expires passwords for accounts that are being attacked, but could not provide a number of accounts expired recently. But it's unclear if the logins of the nearly 7 million other Dropbox users the hackers claim to have are still safe. That means Dropbox has already expired the 400 logins that have been leaked so far. All other remaining passwords have expired as well.

We'd previously detected these attacks and the vast majority of the passwords posted have been expired for some time now.

These usernames and passwords were unfortunately stolen from other services and used in attempts to log in to Dropbox accounts. In a statement, Dropbox denied it was hacked:ĭropbox has not been hacked. The hackers claim to have over 6.9 million email addresses and passwords belonging to Dropbox users. The hackers promise to release more accounts in return for Bitcoin donations. The Next Web was the first to notice the leak on a site called Pastebin, where hackers have already leaked about 400 accounts.
