Exostar Data Breach Class Action Investigation

At Console & Associates, our data breach lawyers are closely examining the recent Exostar data breach. This data breach was disclosed following a cyber security incident involving unauthorized access to Exostar's third-party system, which occurred between October 2023 and April 2024, potentially exposing sensitive personal information of affected individuals.

What Happened?

A recent report from the Attorney General of New Hampshire states that the Exostar data breach occurred due to unauthorized access to sensitive information stored on a third-party system. The company discovered the incident in October 2023 and launched an investigation to determine the scope and impact of the breach. The investigation concluded on November 22, 2024, revealing that an unauthorized party had gained access to and potentially acquired sensitive information over a six-month period.

Data breach letters were sent out by Exostar on December 23, 2024, informing affected individuals about the nature of the incident. While the specific types of compromised data have not been disclosed in public filings, individual notification letters should detail the exact nature of the affected information.

Steps To Take If You Were Affected By A Data Breach

   2. Use a combination of letters, numbers, and special characters
   3. Consider using a password manager for better security
      
      
5. Enable two-factor authentication where possible
