In July 2012, Yahoo's online publishing service "Voices" experienced a significant data breach. The incident highlighted the issue of password reuse.

How many accounts were compromised?

The breach compromised data for approximately 453,000 users.

What data was leaked?

The data exposed in the breach included email addresses and passwords, potentially putting users' personal and professional accounts at risk.

How was Yahoo hacked?

In the 2012 Yahoo! Voices breach, attackers exploited a SQL injection vulnerability to gain unauthorized access to the system, compromising nearly 500,000 usernames and passwords stored in plain text. The incident revealed that 59% of users affected by both the Yahoo! and Sony breaches reused their passwords across both platforms, highlighting the risks associated with password reuse.

Yahoo's solution

In response to the hack, Yahoo! took several measures to enhance the security of its platform and prevent future incidents. These actions included invalidating unencrypted security questions and answers, asking potentially affected users to change their passwords, and hiring a dedicated chief information security officer. Additionally, Yahoo! updated their sign-in page to address security issues and provide users with more information, as well as offering user-friendly guides on recognizing legitimate Yahoo! security notices.

How do I know if I was affected?

Yahoo! reached out to users believed to be affected by the breach. If you were a Yahoo! Voices user and did not receive a notification, you may visit Have I Been Pwned to check if your credentials were compromised.

What should affected users do?

In general, affected users should:

  1. Change Your Password: Immediately update your password for the breached account. Make sure the new password is strong and unique, not previously used on any other platform.

  2. Reset Passwords for Other Accounts: If you've used the same or similar passwords for other online accounts, reset those as well. This is crucial as attackers often try using stolen passwords on multiple sites.

  3. Enable Two-Factor Authentication (2FA): Activate 2FA on the breached account and any other important online accounts. Consider enabling this additional security feature to significantly reduce the risk of unauthorized access.

  4. Monitor Your Accounts: Keep an eye on your accounts for any suspicious activity, and report any unauthorized access or transactions to the appropriate parties.
