Monterey Mushrooms LLC Data Breach (2025)

654After Incident
CRITICAL-110
MON5902759091925
Monterey Mushrooms LLC, the largest fresh mushroom producer in the U.S., suffered a ransomware attack by the INC RANSOM group between August 2–7, 2025. The breach exposed personally identifiable information (PII), including names, driver’s license numbers, passport numbers, and Social Security numbers, posing a high risk of identity theft and fraud. The stolen data was later posted on a dark web leak site (Sept. 5, 2025). While the total number of affected individuals remains undisclosed, the company notified victims via mail and reported the incident to the California Attorney General’s office (Sept. 18, 2025). Monterey Mushrooms secured its IT systems, involved law enforcement, and offered free identity protection services (Epiq Privacy Solutions) to impacted individuals. The breach’s severity stems from the sensitive nature of the leaked data and the potential for widespread financial and reputational harm to victims.
