Dropbox has acknowledged usernames and passwords were stolen from a third-party service.
Hackers claim they have 7 million usernames and passwords and have been posting them on websites including Pastebin and Reddit.
Dropbox said most of the passwords had expired and it has forced a password reset on the rest.
If you are a user of Dropbox, you should also turn on two-factor authentication. This will require you to input a code that was sent to your phone before gaining access to your account from a new device.
Dropbox have been sending emails to the users in the Pastebin “dump” but even if you haven’t been compromised, changing your password and turning on two-factor authentication will protect you in the long run.
