Public filings indicate that unauthorized access occurred within AltaMed's IT environment. The official notification from AltaMed states that if you have received a formal data breach notification letter, it indicates your personal or protected health information may have been involved in this incident.

Such notification letters are designed to inform potentially affected individuals about the event and provide guidance on steps they can take to safeguard their information. Receiving this correspondence means your data was identified as potentially exposed during the security compromise.

To help protect yourself, it is important to remain vigilant for any unusual activity involving your accounts. Closely monitor financial statements and credit reports for any unauthorized transactions or new accounts opened in your name. Any suspicious activity should be reported immediately to the relevant institutions.

Additionally, consider implementing strong, unique passwords for all online accounts and enabling multi-factor authentication wherever it is offered. Be cautious of unsolicited communications, especially those requesting personal details, as these could be phishing attempts. Regularly review and update the privacy settings on your online platforms.

While the investigation into the full scope of this incident is ongoing, taking these proactive security measures can help mitigate potential risks associated with unauthorized data access.
