Burger King saw a surprising upside after its Twitter account was compromised on Monday. The company tweeted: “Interesting day here at Burger King, but we’re back! Welcome to our new followers” Burger King’s followers, which numbered around 50,000 as of Monday evening, shot up to more than 110,000. It was unclear who was responsible for the hack; Twitter officials could not immediately be reached. Earlier this month, Twitter said its servers were breached by “extremely sophisticated” hackers.”]
