Google CEO Sundar Pichai's Quora account hacked

Google CEO Sundar Pichai's Quora account has been hacked by the same group which previously broke into Facebook boss Mark Zuckerberg's Twitter and Pinterest accounts, according to a media report today.
The hacker group called OurMine Team has been posting messages on Quora through Pichai's account. The breach of his account became apparent when tweets linking to his Quora posts appeared on his official Twitter account yesterday.
The Indian-born Google CEO's has 508,000 followers.
The hacker group initially wrote, 'hacked' using his account. "Hey it's OurMine, we are just testing your security, please visit OurMine to upgrade it," it said in later posts, The Verge reported.

Pichai or perhaps his team, however regained control of the Quora account soon, and the tweets were deleted within few hours.
OurMine team claims it is focused on security. It brings out the security flaws in user's account by hacking in to them. "We are just trying to let them know that nobody is safe," OurMine told the online news portal Mic.
After taking credit for Zuckerberg's social media accounts, it also compromised the Twitter account of the microblogging site's co-founder and former CEO Evan Williams earlier this month. Spotify's Daniel Ek was one of its targets too.
It is not clear how the group is gaining access to their accounts. The group claims that it uses various exploits to pull passwords from celebrities' browsers, the report said.
