Impact and risks for MAS Law customers

How to protect against similar security incidents
In light of the MAS Law breach involving sensitive personal information, affected individuals and organizations should adopt the following security measures to mitigate potential risks.
- Enroll in identity monitoring services. MAS Law is offering 24 months of identity monitoring through Kroll for affected individuals. Sign up for these services immediately to receive alerts regarding potential misuse of your personal data.
- Enable phishing-resistant multi-factor authentication. Protect your online accounts by enabling multi-factor authentication (MFA) wherever possible. Use authenticator apps or physical security keys rather than SMS-based codes to prevent account takeover via SIM swapping.
- Monitor financial statements and credit reports. Regularly check bank and credit card statements for any transactions you do not recognize. Consider placing a security freeze on your credit reports to prevent unauthorized parties from opening new accounts in your name.
- Enhance attack surface management. Organizations should utilize continuous monitoring tools to identify and secure vulnerabilities in external-facing systems. Promptly apply security patches and updates to reduce the risk of exploitation by unauthorized third parties.
