Yahoo Says Forged Cookie Attack Accessed About 32 Million Accounts (cnet.com) 30
It looks like Yahoo has yet to reach its lowest point. The company revealed today via a regulatory filing that about 32 million user accounts were accessed by hackers in the past two years using forged cookies that allowed them to log into their accounts without passwords. According to Yahoo, the attack is likely connected to the "same state-sponsored actor believed to be responsible for the 2014 [breach]," which resulted in the theft of user information from 500 million user accounts. CNET reports: "Based on the investigation, we believe an unauthorized third party accessed the company's proprietary code to learn how to forge certain cookies," Yahoo said in its annual filing to the Securities and Exchange Commission. The company went on to say that forged cookies have been invalidated to prevent further use on accounts. Yahoo revealed the attack in December but the news was largely overlooked because the company announced at the same time it had identified a separate security breach that took place in 2013 in which hackers stole information on 1 billion Yahoo accounts. Yahoo CEO Marissa Mayer also revealed today that she is giving yahoo employees her annual bonus to make up for the massive hacks.
