Yahoo discloses another hack, to the tune of 1B user accounts


Yahoo has not had good luck lately. The latest to descend on the tech company is one the company disclosed today saying that it has discovered a breach of more than one billion user accounts that happened back in August of 2013.

According to a report on TechCrunch and other outlets, the developing story states that Yahoo’s chief information security officer Bob Lord has said that the company hasn’t been able to determine how the data from the accounts was stolen.

This is separate from the incident in September that Yahoo reported in September, where theft of data from 500 million accounts occurred in late 2014. After that attack, chief executive Marissa Mayer said that the company was "heartened" by users' loyalty following a mammoth data breach.

In a post announcing the latest attack, Lord stated this: “For potentially affected accounts, the stolen user account information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords (using MD5) and, in some cases, encrypted or unencrypted security questions and answers. The investigation indicates that the stolen information did not include passwords in clear text, payment card data, or bank account information. Payment card data and bank account information are not stored in the system the company believes was affected.”

This story is still developing, meaning more information may be released on the latest hack information.
