Recommended actions
- Change your Ajarn 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 Ajarn — 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.
