In March 2017, the Dueling Network, an online platform for the Yu-Gi-Oh trading card game, experienced a data breach. Although the site had been taken offline in 2016 due to a cease-and-desist order, its forum remained active for another year. Users who may have reused their Dueling Network passwords on other sites were advised to change them immediately to prevent further unauthorized access.
How many accounts were compromised?
The breach impacted data related to approximately 6.49 million individuals.
What data was leaked?
The data exposed in the breach included email addresses, IP addresses, passwords stored as MD5 hashes, and usernames.
How was Dueling Network hacked?
The hacker behind the Dueling Network data breach exploited a vulnerability in MySQL to gain unauthorized access to the platform's database. The compromised passwords were encrypted using the MD5 algorithm, which is known for its vulnerabilities, making it easier for the attacker to decrypt them and obtain plaintext passwords.
Dueling Network's solution
In response to the hack, Dueling Network took down its forum, which had remained active even after the main site was shut down due to a cease-and-desist order. Users were warned to change their passwords, especially if they had reused them on other sites.
How do I know if I was affected?
Individuals who suspect their credentials may have been compromised can check if they were affected by visiting HaveIBeenPwned, a platform that monitors data breaches and can notify individuals if their data has been disclosed in recognized data leaks.
What should affected users do?
In general, affected users should:
Change Your Password: Immediately update your password for the breached platform. Make sure the new password is strong and unique, not previously used on any other platform.
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.
Enable Two-Factor Authentication (2FA): Activate 2FA on the affected account and consider enabling this additional security feature on all other important online accounts to significantly reduce the risk of unauthorized access.
