Stolen username and password combinations, alleged to be for Dropbox accounts, have been posted online. Dropbox is a popular cloud-based storage service.

Dropbox has stated that it has not been breached, but that the usernames and passwords were stolen from ‘other services’ and used in attempts to log in to Dropbox accounts.

It also states that, ‘We'd previously detected these attacks and the vast majority of the passwords posted have been expired for some time now. All other remaining passwords have been expired as well.'

It did not clarify which ‘other services’ might be involved or how many users may have been affected.

At the time of writing, several ‘teaser batches’ containing a few hundred password records, of what is claimed to be almost 7 million passwords, have been uploaded to pastebin. The author is seeking Bitcoin payments to upload more.

As a precaution, if you have a Dropbox account you should change your password immediately.

You should also ensure you have two-step (or two-factor) authentication enabled. If your password is compromised, such as in this breach, the second step means your account should remain safe.
