An anonymous hacker group claims it has access to almost $7 million Dropbox accounts, and for the right price, they intend publishing information.

 
Dropbox issued a statement in their blog saying they have not been hacked.

 
The company said “The usernames and passwords referenced in these articles were stolen from unrelated services, not Dropbox”

 
“We have measures in place to detect suspicious login activity and we automatically reset passwords when it happens.”

For what its worth, it seems Dropbox will reset all affected accounts passwords and its recommending users to turn on two-factor authentication for added layer of protection.

 
The hackers have initially released 1,200 usernames and passwords on Pastebin on October 13, 2014, and are looking to be paid via Bitcoin in order to release more.

UPDATE: Dropbox posted an update regarding this claim saying “A subsequent list of usernames and passwords has been posted online. We’ve checked and these are not associated with Dropbox accounts.”
