“Earlier today, Tesla’s Twitter account and website were taken over by some nefarious jokesters. Around 5 PM ET, a strange tweet popped up on the company’s official Twitter account, suggesting the company was no longer in control of what was being posted. The tweets largely suggested this was just an unsophisticated prank. The hackers posted a phone number saying those who called it could get a free car. The rest of the tweets were mostly shoutouts to random accounts. The Tesla account name was changed to #RIPPRGANG.”
