Yahoo has confirmed that a data breach from 2014 hit 500 million users, allowing hackers access to sensitive information, including poorly encrypted passwords.And now, this (quoting BGR):
A press release from Yahoo confirms the news, and follows reports earlier today that Yahoo was set to confirm the breach. If true, stealing the user credentials from 500 million users would be one of the largest hacks ever to hit a US company.
Intelligence agencies wanted Yahoo to scan all Yahoo Mail emails looking for a specific signature. Apparently, agents of a foreign terrorist organization were communicating using Yahoo “with a method that involved a ‘highly unique’ identifier or signature.” The investigators did not know what email accounts were used, so they needed Yahoo’s help to discover them.Not a good coda for Marissa Mayer's tenure at Yahoo.
