A major brand's Twitter account has been hacked for the second day in a row. Yesterday, Jeep's Twitter account was hijacked and had it's avatar replaced with Cadillac's. Why? Probably just because someone could. The day before, Burger King's account was hacked and was made to look like it was Mcdonald's account. Fortunately, all is well and both brands were able to have fun in the aftermath as they exchanged clever tweets.
Initial reports said that the infamous hacker group Anonymous claimed credit, while other reports indicated @DFNTSC took credit for the attack.
So, how can you protect your account? Simple. Change your password every 30-90 days. And, if you happen to get a DM saying something like: "Hey, someone is saying bad things about you," or "Haha, look at this funny picture of you I found," - don't click the link included, that's how the hackers gain access to your account.
If this does happen to you, try to change your password right away. If that doesn't work, submit a Twitter help desk ticket and they should resolve the problem for you within 48-72 hours.
Be sure to protect all of your social accounts!
