Yahoo closes security hole that led to password breach

Share this article:

Yahoo said Friday that it has fixed a security vulnerability that allowed hackers to seize roughly 450,000 unencrypted email addresses and passwords belonging to members of its content-sharing platform.

In a blog post, the web giant said the intruders accessed a "standalone file" that contained the login data used by writers who joined Associated Content  prior to May 2010, the month when Yahoo acquired the company for $100 million. Now called Yahoo Contributor Network, the business unit specializes in producing freelancer-generated, search-optimized content.

According to experts, the hackers, which claimed to be part of a relatively unknown contingent known as "D33ds Company," obtained the information in clear text through a SQL injection attack, a common technique used to infiltrate vulnerable web applications.

"We have taken swift action and have now fixed this vulnerability, deployed additional security measures for affected Yahoo users, enhanced our underlying security controls and are in the process of notifying affected users," the post said. "In addition, we will continue to take significant measures to protect our users and their data."

The company did not specify.

Affected users will be asked to answer a series of challenge questions to enable them to reset their credentials.
