Attorneys at Almeida Law Group are investigating whether a class action lawsuit can be filed on behalf of individuals affected by a possible ADM data breach. According to dark web monitoring sources, a hacker group calling itself qilin claimed responsibility for a cyberattack on ADM in a post first observed in September 2026, alleging it had gained access to internal company systems. As of this writing, ADM has not issued a public confirmation of the incident, and the exact scope of any exposed data remains unknown. If you believe you were affected, contact Almeida Law Group.
About ADM
Archer Daniels Midland Company (ADM) is one of the world’s largest agricultural supply chain managers and processors, headquartered in Chicago, Illinois. Founded in 1902 and incorporated in Delaware in 1923, the company produces, processes, transports, stores, and merchandises agricultural products, commodities, and ingredients across three business segments: Ag Services and Oilseeds, Carbohydrate Solutions, and Nutrition. ADM operates globally with over 270 plants and 420 crop procurement facilities worldwide, reporting approximately $80.27 billion in annual revenue as of 2025.
What Happened?
On September 15th, 2026, the Qilin ransomware group listed ADM (adm.com) on its dark web leak site, as reported by Ransomware.live. This is solely an attacker-side allegation. No description of the incident, data samples, claimed data volume, or ransom demand details were included in the claim. ADM has not publicly confirmed or acknowledged any breach or ransomware incident. No independent corroborating sources — including news outlets, regulatory filings, or official company statements — were found to confirm the claim. Because ADM is a publicly traded Fortune 50 company, any confirmed material cybersecurity incident would likely require disclosure in an SEC Form 8-K filing; no such filing was identified.
Qilin, also known as Agenda, is a Russian-speaking Ransomware-as-a-Service (RaaS) operation active since August 2022. The group has claimed more than 2,200 victims across 62 or more countries and employs double extortion tactics, combining file encryption with data exfiltration. Notable alleged Qilin victims include the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) in August 2026, NHS pathology provider Synnovis in June 2024, Nissan, and Lee Enterprises. No arrest, indictment, sanction, or joint advisory has been issued against Qilin as of August 2026. ADM’s most recent annual filings disclosed an increase in cyberattack volume, frequency, and sophistication, with the company’s 2026 10-K specifically noting email phishing attacks, ransomware, and industrial espionage as elevated risks.

What Should You Do?
Even though ADM has not confirmed a breach, it is reasonable to take precautionary steps if you have a relationship with the company. Consider placing a fraud alert or credit freeze with the three major credit bureaus — Equifax, Experian, and TransUnion — to help prevent unauthorized accounts from being opened in your name.
