Belkorp Ag Data Breach Exposes Sensitive Info of Many

Belkorp Ag, a leading California-based agricultural equipment dealer, experienced a major data breach. On or about April 26, 2025, the company detected suspicious activity within its network. An investigation determined that a cybercriminal gained access between April 18, 2025 and April 26, 2025, and copied sensitive data.

On May 20, 2025, a threat actor known as “hensi” claimed responsibility for the attack on openweb forums, alleging to have obtained the company’s complete network data, full database, over 1,000 PDF employee forms containing Social Security numbers, and budget information spanning 2015 to 2025.

A review was launched and on Sept. 2, 2025 revealed that the cyberattack compromised personally identifiable information (PII). Exposed information included names, Social Security numbers, dates of birth, driver’s license numbers, passport numbers, financial account information, biometric data, medical record numbers, health insurance coverage information, payment for health services, medical diagnosis and treatment information, and dates of treatment.

Belkorp AG began notifying affected individuals by mail on Sept. 29, 2025. The breach was officially disclosed to multiple state authorities, including the California Attorney General, Massachusetts Attorney General, Montana Attorney General and New Hampshire Attorney General on Sept. 29, 2025.

The company also posted a Notice of Data Breach on its website.
