Yahoo Admits It Has Been The Subject Of World’s Biggest Hack
Just two days after Yahoo admitted hackers had raided its database of at least 500 million accounts, plaintiffs are lining up to file suits claiming negligence. Already two Californian Yahoo users have filed the class-action claim, citing failure by Yahoo to take due care of sensitive information, plus claims of negligence over its poor security.
The Internet company, which has agreed to sell its core business to Verizon Communications, admitted that hackers penetrated its network in late 2014 and stole personal data on more than 500 million users.
The data included names, e-mail addresses, dates of birth, telephone numbers and encrypted passwords, Yahoo said.
Yahoo believed the hackers were no longer in its network and pointed the finger at the work of another nation, such as Russia, which over the past year has taken China’s place as the primary suspect of attacks on US systems.
The Yahoo data could be used to obtain the personal correspondence of public figures, according to Matthew Green of Johns Hopkins University.
“For a government, the real value would be to look for people with real value ( high net worth),” he said.
Yahoo said the stolen passwords were encrypted, but experts said that a determined attacker could unscramble passwords using commonly available “cracking” software.
The disclosure of the data theft comes as CEO Marissa Mayer steers the company towards the planned sale for $4.8 billion to Verizon Communications.
