What Caused the Lyon Real Estate Breach?

The Lyon Real Estate data breach was only recently announced, and more information is expected in the near future. However, Lyon’s filing with the Attorney General of California provides some important information on what led up to the breach. According to this source, on approximately May 4, 2023, Lyon detected suspicious activity within its IT network. In response, Lyon launched an investigation into the incident with the assistance of cybersecurity experts.

Lyon’s investigation ultimately confirmed that an unauthorized party was able to access portions of its IT network on various dates between April 18, 2023 and May 4, 2023. Evidently, the unauthorized party gained access to Lyon’s systems through a vulnerability in a vendor’s application that was used by Lyon. It was also determined that the unauthorized party obtained confidential information stored on the company’s computer system.

After learning that sensitive consumer data was accessible to an unauthorized party, Lyon Real Estate reviewed the compromised files to determine what information was leaked and which consumers were impacted. However, the publicly available data breach letter from Lyon Real Estate does not list the specific data types that were subject to unauthorized access, as this portion of the letter was redacted.

However, on September 6, 2023, Lyon Real Estate sent out personalized 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.
