Google chief executive Sundar Pichai's Quora account was compromised today as part of what appears to be a targeted attack by the OurMine hacking group on several high-profile technology executives' social media accounts.
Pichai's Quora crowd knowledge forum account was linked to his Twitter account, and reposted what the hackers wrote on the forum to the microblogging network.
Tweets such as "is it possible to force my android app users of all versions to update the app" went out to Pichai's over half a million followers on Twitter thanks to the account integration.
The hackers are believed to be the OurMine group, which earlier this month compromised Facebook founder Mark Zuckerberg's Twitter and Pinterest social media accounts.
Twitter chief executive Dick Costolo also revealed OurMine also appeared to have compromised another of his accounts on a linked service to cross-post to Twitter just over a week ago.
And Twitter co-founder Evan Williams's account on the social network was similarly compromised by OurMine through a linked Foursquare account.
OurMine has not detailed the reason for the attacks. Its members have not yet been identified.
Google has been contacted for comment.
