WHMCS data breach

What happened

In May 2012, the web hosting, billing and automation company WHMCS suffered a data breach that exposed 134k email addresses. The breach included extensive information about customers and payment histories including partial credit card numbers.

What data leaked

• Email addresses
• Email messages
• Employers
• IP addresses
• Names
• Partial credit card data
• Passwords
• Payment histories
• Physical addresses
• Website activity

What to do if you had an account

1. Change the password. Change your password on this service. If you used the same password anywhere else, change it there too: attackers try leaked email and password pairs on other sites automatically. A password manager makes one unique password per site practical.
2. Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
3. Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
4. Check your bank statements. Review recent card and account transactions and report anything you do not recognise. If full card numbers were exposed, ask your bank to replace the card.
