Dropbox reportedly “appears” to have been hacked after anonymous hackers claimed to have compromised some 7 million accounts with several hundreds of usernames and passwords leaked in plain text so far, and with full leak promised if they received donations to their bitcoin address.
Dropbox, however, has denied claims of any data breach:
“Dropbox has not been hacked. These usernames and passwords were unfortunately stolen from other services and used in attempts to log in to Dropbox accounts. 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.”
Advice: Change your password immediately. And just like the recent iCloud hack, think hard before you post anything personal and confidential online.
