“The investigation has found no evidence that the state-sponsored actor is now in Yahoo’s network”, the company said.

The breach first caught the headlines last August when hacker “Peace” went in the dark web announcing the sale of over 200 million Yahoo accounts.

Telecommunications company Spark says it’s still trying to working out whether its customers have been affected after 500 million Yahoo clients had information from their accounts stolen. The company says it’s using email to notify those who were potentially affected; it’s also urging users to change their passwords.

Yahoo who in Australia partner with the Seven Network, has admitted to a hack in 2014 that left data of 500 million users exposed. It’s recommended that users change their passwords for non-Yahoo accounts if they use the same password.

Yahoo however denied that the breached was an inside job, saying there is no evidence that the “state sponsored actor” is now in Yahoo’s network.

Account passwords were also copied by the hacker, but were hashed in most cases with the bcrypt function, which is considered resistant to brute-force cracking attempts.

Through strategic proactive detection initiatives and active response to unauthorized access of accounts, Yahoo will continue to strive to stay ahead of these ever-evolving online threats and to keep our users and our platforms secure.

Verizon said it still doesn’t know enough about the Yahoo break-in to assess the potential consequences. According to GameSpot sister site CNET, Verizon said it was made aware of the breach earlier this week, at which time it had “limited information and understanding of the impact”. Verizon said in a statement Thursday that it was notified of the hack “within the last two days”, and now has “limited information and understanding of the impact”.
