(JTA) — Facebook founder Mark Zuckerberg had some of his social media accounts hacked.
Zuckerberg’s Twitter and Pinterest accounts were hacked Sunday by a hacker group called OurMine, according to reports.
The group reportedly discovered Zuckerberg’s password during a breach in the LinkedIn database. His password reportedly was not very strong – the hackers said it was “dadada” — and was used on multiple accounts, which are cardinal social media sins. He also reportedly had not used those accounts very often.
The hackers tweeted from Zuckerberg’s Twitter account and changed the title of his Pinterest page. Both accounts later were returned to Zuckerberg and the posts were deleted.
Hackers also claim they have accessed Zuckerberg’s Instagram account, a Facebook-owned application on which Zuckerberg is active.
