Exposed data

Recommended actions

• Change your AnimeLeague 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 AnimeLeague — attackers weaponise breach data quickly.
• Stay alert for smishing (SMS phishing) and SIM-swap attempts using your phone number.
• Exposed identity data raises identity-theft risk — consider credit monitoring or a credit freeze.
