Zuckerberg’s own Facebook account got hacked in breach

Red-faced Facebook founder Mark Zuckerberg and two of his top execs were among the 50 million users of the social media site whose accounts have been hacked.

“This is a really serious security issue, and we’re taking it seriously,’’ Zuckerberg [pictured] said on Friday. “We need to be more proactive.’’

Other hacking victims include Facebook’s chief operating officer, Sheryl Sandberg, and its European vice- president, Nicola Mendelsohn.

Hours after the hack was revealed, a class action suit was filed against Facebook by users Carla Echavarria of California and Derrick Walker of Virginia. Some speculated it could turn out to be the biggest such suit ever filed.
