Hundreds of Dropbox user login credentials were posted on Pastebin yesterday by a user who claimed to have 7 million more username-password combinations at the ready.

Security experts say the real problem is single-factor authentication, which is needed to prevent password-based attacks, says Jason Hart.”]
