Yahoo’s claim that it is the victim of a gigantic state-sponsored hack raises the question of whether it is the latest target for hackers with the backing of Russia, China or even North Korea, experts say. The US internet giant was under pressure Friday to explain how it sustained such a massive breach in 2014, which possibly affected 500 million accounts.
Yahoo said the stolen information may have included email addresses and scrambled passwords, along with both encrypted or unencrypted security questions and answers that could help gain access to victims’ other online accounts.
