Yahoo: Hackers stole 1bn users’ data

Yahoo has said it believes hackers stole personal data from more than 1bn user accounts as part of a cyber attack that occurred in 2013.

The technology giant said it believes the attack is “distinct” from another cyber attack the company reported last September, which involved around 500m accounts and was said to have been carried out by a “state-sponsored actor” in late 2014.

Yahoo says this personal data affected included “names, email addresses, telephone numbers, dates of birth, hashed passwords”, as well as security questions and answers, but the company claimed financial information had not been compromised.
