Mark Zuckerberg’s Twitter and Pinterest accounts hacked, possibly due to an awfully weak password

Mark Zuckerberg doesn’t tweet much — in fact, he hasn’t used that social network, in many ways a competitor to his Facebook, in four years. So when an unusual message appeared on his account Sunday, people took notice.

As it turns out, it wasn’t Zuckerberg doing the tweeting — it was a notorious hacker group called OurMine, who briefly gained access to his Twitter and Pinterest profiles.
