The Battery San Francisco Data Breach Investigation

The Battery reported a data security incident to the California Attorney General in March 2026, and notification letters began reaching affected individuals on March 26, 2026. Contact our data breach lawyers to learn more about the incident.

What Happened?

According to the breach notice filed with the California Attorney General, The Battery experienced a network disruption on or around November 15, 2025. This disruption affected certain systems and prompted the company to launch an internal investigation with the help of cybersecurity specialists.

That investigation revealed that an unauthorized third party had accessed The Battery's systems during a window spanning November 11 through November 15, 2025. The attacker may have accessed sensitive personal information stored within those systems. After completing a review to identify the scope of the incident and the individuals affected, The Battery began mailing data breach notification letters on March 26, 2026.

That means roughly four and a half months passed between the initial intrusion and the date when affected individuals received notification. Under California's data breach notification laws, companies are required to notify affected residents in the most expedient time possible and without unreasonable delay.

What Information Was Exposed?

The data breach potentially exposed the following categories of personal information:

• Full legal name
• Social Security number
