Unconfirmed reports from the Chaos ransomware group in June 2026 claim a data breach at Graymont, a company specializing in construction and mining materials. The ransomware group stated they gained full access to Graymont's corporate infrastructure and possess a large volume of sensitive data. However, Graymont has not issued any official statement or breach notification, and no regulatory body has confirmed the incident. Because the claim is not supported by official sources, no official statement, no official breach notification letter, and no number of individuals notified currently exist in the public record. Details regarding the types of data compromised, the number of individuals affected, and the states impacted remain unconfirmed. There is no evidence this is a vendor or third-party breach affecting other customers. Until Graymont issues an official breach notification, all details remain speculative and unverified.
It is important to note that information about data breaches can emerge over time, and official notifications may be delayed. The situation is currently being monitored for further developments.
