back to article Carbonite online backup accounts under password reuse attack

If you're a user of online backup service Carbonite, you're getting a new password. Don't make it one you've used somewhere before. Carbonite has released a statement telling users it's run a system-wide password reset in the face of a password-reuse attack. The company claims its own systems haven't been compromised, but if …

      It's all about the patterns. Clearly Carbonite were seeing multiple logins from a new range of IP Addresses. I'd assume that Carbonite keeps track of IP Addresses where the software is running.

        they are handling it really well. (ive got 200 odd customers on carbonite)
