After a slew of racial epithets, Cadillac quickly distanced itself, tweeting, "Just to clarify, Cadillac is not connected to the hack of the @Jeep Twitter account." And after alerting Twitter, the company seems to have regained control of its account, with the offending Tweets taken down.
A short time later, MTV's Twitter account appeared to be hacked, but it turned out to be a publicity stunt by the company.
Who did it?
The hacked Jeep account sent a tweet addressing two hacker groups, LulzSec and Anonymous, so they're expected to have some connection. And there's some speculation that a New England DJ was responsible.
The @Jeep hack attack comes as Apple announced some of its computers were victim to the same hackers that attacked Facebook.

And just 24 hours ago @BurgerKing's Twitter account was hacked by what looks like could be the same hacker. In the 71 minutes that Burger King was hacked, 53 tweets were sent with a total of 73,421 retweets. Burger King addressed the issue, saying "Interesting day here at Burger King, but we're back! Welcome to all our new followers. Hope you all stick around!"

These kind of hacks could have happened by something as simple as resetting a compromised email account. This appears to be a problem with the security of the accounts—a web issue—and not a problem Twitter is directly responsible for.
At the beginning of the month, Twitter reported that hackers gained access to its internal information and compromised 250,000 accounts. Twitter reset passwords for those accounts, and urged "all users to take this opportunity to ensure that they are following good password hygine, on Twitter and elsewhere on the Internet."

Twitter said it doesn't comment on individual accounts. The company has made a big push to help users strengthen their passwords. It has automatic tools and employees who constantly monitor for hack attacks, and has people on staff who are focused on ways to improve security and educate users about best practices. Twitter works with brands and individuals to go over password best-practices and guidelines, but if this kind of high-profile hack continues, they may have to do more.
