Last Pass Forces Users to Pick Another Password

Summary: LastPass forced all of its approximately 1.25 million users to change their master passwords after spotting a "traffic anomaly" - unexplained data transfers - from one of its databases on Tuesday morning. LastPass said the transfer was large enough to have moved email addresses, the server salt and salted password hashes, but not large enough to have pulled many users' encrypted data blobs.

Why it matters: The exposure matters because the threat is brute-forcing a weak master password with dictionary words and then presenting it to LastPass to retrieve the encrypted data - and LastPass's own blog acknowledged not everyone picks a master password immune to that. Users changing their master password from an unrecognized internet address had to validate their email first, and commenters reported being locked out of accounts and unable to reach the email needed to validate.
