“InfoArmor concluded the Yahoo hackers were criminal after reviewing a small sample of compromised accounts, Andrew Komarov, the firm’s chief intelligence officer, said in an interview.
The hackers, dubbed Group E, have a track record of selling stolen personal data on the dark web, and have been previously linked to breaches at LinkedIn, Tumblr and MySpace, Komarov said.
‘They have never been hired by anyone to hack Yahoo,’ Komarov, who is from Russia, said. ‘They were simply looking for well known sites that had many users.'”
