He might be running a world's biggest social
networking site but he is also prone to cyber
attacks because of bad password security.
Undoubtedly he is maintaining a top notch security on his Facebook properties but not on other's properties. Some of his social media accounts got hijacked on Sunday and attackers were posting messages to show off their access.
The team behind this hack is OurMine Team, they managed to hack into Mark's Twitter and Pinterest account and they have also claimed to have accessed to Mark's Instagram account, although Facebook has denied this to several media companies.
According to OurMine Team, Mark used the same password for Twitter and Pinterest account as he used in his LinkedIn account ("dadada").
Note: All his accounts have been restored now and the rogue posts have been removed as well.
