Google CEO Sundar Pichai seems to have been the latest target of Ourmine, the group who claimed responsibility for hacking into Mark Zuckerberg’s social media accounts earlier this month. The group made several posts to Pichai’s Twitter account, broadcast to his 5,08,000-plus followers, from his Quora account, and claimed to have hacked into both.

However, unlike the Zuckerberg hack, where entry was gained into his accounts using a password obtained from the massive leak of LinkedIn data, access to Pichai’s Quora account seems to have been via a vulnerability on the question-and-answer website’s end. Ourmine claims to have reported this vulnerability to Quora, with no response, according to The Next Web.
