Yahoo! has moved to alleviate concerns over a security breach which saw the user details of over 450,000 accounts stolen in a hacking incident last week (July 12).
Officials from the company, which provides a range of online services such as news and a question and answer forum, confirmed that they have determined the cause of the breach and moved to patch the vulnerability in a blog post dated July 13.
"Yahoo recently confirmed that an older file containing approximately 450,000 e-mail addresses and passwords was compromised … this compromised file was a standalone file that was not used to grant access to Yahoo systems and services," said Yahoo.
"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."
Yahoo! has asserted that it will continue to take significant measures to enhance vulnerability management of confidential data and ensure that users are protected from further incidents of this nature.
Nonetheless, the security breach stands as a stark reminder of the importance of undergoing a regular security audit to ensure that your company is protected from potential cybercrime incidents.
Yahoo! users who attempt to log in to their accounts can expect to be asked a series of authentication questions to confirm that they have not been the victim of an unauthorised access attempt.
