An account belonging to Pichai on Quora, a question-and-answer social network, appeared to have been briefly hijacked on Sunday by OurMine. The same group claimed to have accessed Mark Zuckerberg's Twitter account earlier this month.
After gaining access to Pichai's Quora account, the group was able to send linked tweets to Pichai's Twitter account, where the CEO has more than half a million followers.
Hacking high-profile targets seems like an unorthodox way to get business attention, but that appears to be OurMine's strategy.
"We are just testing your security," the hackers wrote from Pichai's account. They directed readers to learn more about OurMine's cyber-security services for hire, which range in price from $100 for a social media scan to $5,000 at the corporate level.
A spokesperson for the group told The Next Web: "We are just testing people security [sic], we never change their passwords, we did it because there is other hackers can hack them and change everything."
