Exposed data

Recommended actions

• Change your WHMCS password immediately, and update it anywhere you reused the same password.
• Enable two-factor authentication on the affected account and on your critical services (email, banking).
• Watch for targeted phishing emails referencing WHMCS — attackers weaponise breach data quickly.
• Monitor your bank and card statements closely and consider requesting a card replacement.
• Exposed identity data raises identity-theft risk — consider credit monitoring or a credit freeze.
