Hundreds of usernames and passwords for online document-sharing site Dropbox were published on Pastebin, an anonymous information-sharing website, on Monday.

The user who revealed the information, who claims to have hacked somewhere around 7 million accounts, wants Bitcoin donations to fund the operation.

"We will keep releasing more to the public as donations come in, show your support," the anonymous Pastebin user said on the site, according to Reuters.

Dropbox said in a statement that it has not been hacked however.

"Recent news articles claiming that Dropbox was hacked aren't true. Your stuff is safe. These usernames and passwords were unfortunately stolen from other services and used in attempts to log in to Dropbox accounts," a Dropbox spokesman said in an email to Reuters.

"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," he added.

In a previous statement the company said that it "previously detected these attacks," adding that a number of the passwords posted have "been expired for some time now."

The Silicon Valley startup company has been a hit with consumers and boasts more than 200 million users just six years after it started, according to Reuters.

The company has undergone tremendous growth amid the rise of cloud, which should continue to do well alongside mobile computing.

NSA whistleblower Edward Snowden said last week to those worried about their privacy that they should get "rid of Dropbox" and to stop using their Facebook account and Google in general.
