Some Dropbox users have begun reporting that their accounts are under attack from spam, but what’s more troubling is that, in select cases, the spam is hitting accounts where users claim their email address is only used on Dropbox and not elsewhere on the web. In other words, it’s a unique and private email address, which means there’s an increased possibility that the spam may be related to an address leak on Dropbox’s part.
That’s not necessarily the case, however. Spambots sometimes try random emails until they get a hit, the users may have malware on their PCs which has captured their email through other methods (like a keylogger, for example), and there’s a chance that another third-party app which integrates with Dropbox may actually be the source of the problem. Dropbox is looking into these claims right now, according to the latest official word from the company.
The user complaints first showed up on the Dropbox forums, where, eight hours ago, a company representative called “Joe” stated that Dropbox is: “actively investigating your reports” and “if you have any additional information, please email email@example.com, and we’ll be sure to follow up.”
Many of the affected users initially appeared to be located in Germany, and much of the spam comes from a spammer called “Euro Dice Exchange,” from early reports. However some users claim to have received different spam messages, and others outside of Germany (in the Netherlands and U.K., mainly) have also been affected according to both forum messages and tweets. We’re not seeing any reports of Dropbox U.S. users targeted, though. Let us know if you were.
You can see many of the “Dropbox spam?” tweets here, for instance.

It’s too soon to point fingers at Dropbox as the source of the leak, despite the flare-up. But we reached out to the company around 45 minutes ago with a request for more details. Dropbox communications can be slow to turn around responses, so we’ll update this post with news as it comes in.

Dropbox was founded in 2007 by Drew Houston and Arash Ferdowsi. Frustrated by working from multiple computers, Drew was inspired to create a service that would let people bring all their files anywhere, with no need to email around attachments. Drew created a demo of Dropbox and showed it to fellow MIT student Arash Ferdowsi, who dropped out with only one semester left to help make Dropbox a reality. Guiding their decisions was a relentless focus on crafting a...
