If you're one of Twitter's 320 million users, you need to be aware of a possible breach by a hacker group. Twitter is cautioning some of its users to be on the lookout.
This isn't an ordinary warning from Twitter, either. If it turns out to be correct, it's likely a rogue government is trying to steal your phone number, email address and IP address.
Twitter has been sending out alerts, saying that a "state-sponsored" attack may be underway. (See photo on the next page.)
Twitter hasn't said which government is up to no good. But in the past, we've told you about hackers with ties to Russia and Chinese hackers breaking into heavily protected accounts, including the White House's official emails.
