[GENESIS] – Ransomware Victim: Heimbrock

AI Generated Summary of the Ransomware Leak Page

On October 27, 2025, a ransomware leak post attributed to the GENESIS group identifies Heimbrock as the victim. The header “Heimbrock – GENESIS” frames Heimbrock as a national refractory contractor and the surrounding text reproduces a description of the company’s operations: refractory, acid-proofing, and industrial furnace and masonry services dating back to 1890. The page references Heimbrock’s business context, including an approximate revenue figure of $10 million, and defangs the company website (for example, hxxps://www[.]Heimbrock[.]com). The leak indicates that a negotiation log will be included, and attributes the incident to ill-advised tactics by a representative acting on behalf of the company, suggesting a dispute with a third party rather than a straightforward technical compromise. The attackers note they are open to dialogue when reasonable but will monitor deadlines and requirements going forward, and the post indicates a claim URL is present on the leak page. No screenshots or other images are identified, and there are no downloadable files listed in the provided data. The excerpt does not disclose a specific ransom amount or the exact nature of any exfiltrated data.

The post date appears to be October 27, 2025, which is treated as the publish date given the absence of a separate compromise date in the data. Heimbrock is based in the United States. The page emphasizes the company’s long history and the cited revenue to establish credibility, and it references the defanged company site as context. The content is presented under the GENESIS label and mentions that a negotiation log will be published as part of the leak. There is no explicit information in the provided material about encryption, the specific data types alleged to be compromised, or any ransom amount. The metadata shows no images and no downloadable content on the leak page, reinforcing that the visible excerpt is primarily textual and contextual rather than a data dump. Overall, the page frames Heimbrock as a ransomware victim with a negotiation-forward narrative and a claim URL, but does not disclose a concrete ransom figure in the available material.
