Hackers have stolen more than 68 million account details for online cloud storage platform Dropbox. Last week, Dropbox urged users to change their passwords as a “preventive measure.”
Specifically, users who signed up for the service before mid-2012 were prompted to choose a “new and strong password.”
This is due to the data breach that is said to have affected more than 68 million accounts compromised during a hack that took place roughly four years ago.
Motherboard, a tech site, said it had four files, totaling 5GB in size, which apparently contained e-mail addresses and hashed passwords for 68,680,741 Dropbox users.
Multiple sources have confirmed the authenticity of the user data.
According to Dropbox, the password reset it initiated last week covered all of the affected users so that their Dropbox accounts are protected.
Dropbox, which has around 500 million registered users, is the fourth major company this year to have found user credentials stolen in a 2012 hack circulating online.
