Facebook CEO Mark Zuckerberg is also not that much cautious about his passwords. Yesterday a hacker group called OurMine Team hijacked Zuckerberg’s Twitter and Pinterest accounts and the hackers claimed the Zuckerberg ‘s password “dadada” was leaked through a massive data breach on LinkedIn in May, with more than 164 million users’ data stolen.
The hack implies Zuckerberg reused passwords across multiple sites or perhaps that the format of the password he chose for other sites was guessable after breaking his LinkedIn login credentials.
The group claiming responsibility for the high-profile hacking left a taunting message on both social media accounts. “Hey @finkd, you were in Linkedin Database with the password “dadada,” the team wrote from Zuckerberg’s Twitter page. On his Pinterest, the new title was “Hacked by OurMine Team.” In a deleted tweet, OurMine claimed it also breached Zuckerberg’s Instagram (which Facebook owns) claiming it was “just testing your security.” Zuckerberg’s Facebook account was not affected.
The affected accounts were rapidly re-secured, hopefully with a stronger password, and cleaned up. In a statement, Facebook said: “No Facebook systems or accounts were accessed. The affected accounts have been re-secured.”
Mark Zuckerberg’s Twitter and Pinterest accounts hack following the LinkedIn attack goes to show the serious extent to which password re-use, and simple forms of authentication, can have huge knock on effects to online security.
