What Caused the Data Breach Affecting Aquent?

The Prospect Medical Holdings / Aquent data breach was only recently announced, and more information is expected in the near future. However, Prospect Medical’s filing with the Attorney General of Massachusetts provides some important information on what led up to the breach.

According to this source, Prospect Medical and its subsidiaries, including Prospect Medical Systems, LLC, provide administrative services to CIGNA on behalf of Aquent. On August 1, 2023, Prospect Medical identified unusual activity within its computer network. In response, Prospect Medical took steps to contain the incident and launched an investigation.

The Prospect Medical investigation determined that an unauthorized party was able to access Prospect Medical’s computer network between July 31, 2023 and August 3, 2023. During this time, an unauthorized party accessed and acquired files containing confidential information belonging to members of certain CIGNA health plans. Prospect Medical, through a subsidiary, provides administrative services for healthcare providers who contract with CIGNA, which is how Prospect Medical came to possess CIGNA customer data. On September 29, 2023, Prospect notified CIGNA about the breach.

While the nature of this breach is confusing, it appears that CIGNA provided customer information to Aquent, which then provided the information to Prospect Medical. At no time did hackers gain access to CIGNA’s or Aquent’s computer network, as hackers were able to obtain the information by attacking Prospect Medical’s network.

After learning that sensitive consumer data was accessible to an unauthorized party, Prospect Medical Holdings reviewed the compromised files to determine what information was leaked and which consumers were impacted. While the breached information varies depending on the individual, it may include your name, Social Security number, address, date of birth, diagnosis, lab results, medications, and other treatment information, health insurance information, dates of treatment, and financial information.

On January 31, 2024, Prospect Medical Holdings sent out data breach letters to anyone who was affected by the recent data security incident. These letters should provide victims with a list of what information belonging to them was compromised.
