Dropbox confirmed that a four-year-old security breach exposed not only e-mails but also the hashed passwords of some 68 million users. The company however insisted that there was “no indication” the accounts had been “improperly accessed.”

“There have been many reports about the exposure of 68 million Dropbox credentials. The list of email addresses with hashed and salted passwords is real, however we have no indication that Dropbox user accounts have been improperly accessed,” the company said in a press release distributed on Wednesday.

The file hosting service said that millions of surfaced credentials date back to 2012, and had likely been compromised back then. The company claimed it become aware of the list only two weeks ago and received a copy of the hacked accounts list just “several days ago.”
