[Updated 2:55 p.m. Feb. 19: MTV was also believed to have been hijacked, but the TV network has said on its Twitter account as well as BET's that the hack was fake.]
The Twitter page for Jeep was changed to look like that of Cadillac's after Jeep's profile picture was replaced by the logo of its competitor.
"We got sold to @Cadillac because we caught our employees doing these in the bathroom =[." said a tweet sent from the hijacked Jeep account that included a picture of pain medicine.
"We're aware of the issue and are working to resolve it as quickly as possible," Jeep's head of brand communications, Todd Goyer, told auto blog Jalopnik.
As of early Tuesday afternoon, the Jeep account seemed to be restored.
Gizmodo is pointing at a New England man as the possible person behind the attacks on Jeep and Burger King. The man has social media accounts under the name iThug, which was tweeted by the Burger King and Jeep accounts when they were hacked.
