Los Angeles County Department of Health Services Phishing Attack
The Los Angeles County Department of Health Services was recently targeted in a phishing campaign that saw 23 employees tricked into disclosing their email account credentials after clicking a hyperlink in an email that appeared to have been sent by a trusted sender. The email accounts were accessed by an unauthorized third party between February 19, 2024, and February 20, 2024.
The Department of Health Services said the attack was reported to law enforcement which recommended delaying notifying the affected individuals so as not to interfere with the investigation. Notification letters have now been mailed to the affected individuals who have been provided with information on the steps they can take in response to the breach. The types of data exposed varied from individual to individual and may have included one or more of the following: first and last name, date of birth, home address, phone number(s), e-mail address, medical record number, client identification number, dates of service, and/or medical information (e.g., diagnosis/condition, treatment, test results, medications), and/or health plan information.
The Department of Health Services has sent awareness notifications to all members of the workforce reminding them to be vigilant when opening emails, has enhanced its training regarding identifying and responding to phishing emails, and has implemented further controls to minimize the risk of further successful attacks.
