(CBS Charlotte) — Over the past day, Twitter accounts belonging to Burger King and Jeep have been hacked.

Yesterday, Burger King was the first victim. The fast-food chain had its profile picture changed to resemble McDonald’s Twitter account.

The hackers, who have yet to be identified, tweeted on Jeep’s Twitter account that the company had been “sold to Cadillac.” Additionally, the hackers posted profanity, racial slurs, and photos of a competitor’s car.

Several other unauthorized tweets were posted to the account, and the profile description was changed to read: “The official Twitter Handle for the Jeep – Just Empty Every Pocket, Sold To Cadillac =[ #OpMadCow #OpWhopper.”

Followers of Jeep’s Twitter handle notified the company about the questionable tweets — and the tweets were removed within an hour and a half of the account being compromised.

Around the same time, MTV’s Twitter account appeared to have also been hacked, as it displayed the BET logo. However, both companies are owned by Viacom, and it was later confirmed that this was a PR stunt to draw attention to both networks.

There has been some speculation that the hacker group LulzSec, which is a division of Anonymous, are responsible for the unauthorized tweets. However, at this time, no one has taken responsibility for hacking into the above mentioned Twitter accounts.
