An employee serves customers at the Burger King fast food restaurant in Marseille's airport, in Marignane, southern France, on December 22, 2012. Burger King sustained a virtual Big Mac attack Monday when its Twitter account was apparently hacked then redesigned with a bogus claim of a corporate takeover by McDonald's.

Burger King sustained a virtual Big Mac attack Monday when its Twitter account was apparently hacked then redesigned with a bogus claim of a corporate takeover by McDonald's.

Its @BurgerKing account briefly sported the McDonald's golden arches logo, a curt statement that Burger King "just got sold to McDonald's" and tweets promoting Chicago rapper Chief Keef before it was abruptly suspended.

There was no immediate comment from .

On its own Twitter feed, McDonald's said: "We empathize with our @BurgerKing counterparts. Rest assured, we had nothing to do with the hacking."

Meanwhile, a spokesman told AFP by email: "We don't comment on individual accounts for privacy and security reasons."

It was unclear if Keef had any role in the incident. According to the AllHipHop.com music blog, the 17-year-old is currently serving a 60-day sentence in juvenile detention on a gun charge.

Monday was Presidents' Day, a public holiday in the United States.
