On Thursday, Internet giant Yahoo said that the personal information of at least 500 million of its users had been compromised in a hack which, the company claims, was carried out by a suspected "state-sponsored actor."
The user-data hack revealed by Yahoo is apparently the largest known breach of user information in history.
Revealing that the hack took place in 2014, Yahoo said that the data which the hacker managed to steal from nearly 500 million Yahoo accounts included user names, email addresses, street addresses, phone numbers, and hashed passwords. However, the company has asserted that no financial information has been obtained by the hacker.
In reporting the massive hack of Yahoo users' data, the company also said that there is "no evidence that the state-sponsored actor is currently in Yahoo's network."
Meanwhile, though the disclosure of the hack came as a surprise for Yahoo users, officials in Washington were seemingly not as surprised, because government technology managers had been warning them, for more than one year, that their personal Yahoo email was being targeted by hackers.
