AI Generated Summary of the Ransomware Leak Page

The leak page centers on J. E. Stacey & Co. Ltd (jestacey[.]com), identified as a victim in a ransomware data-leak post. The company is described as a privately owned building and civil engineering contractor based in Holsworthy, Devon, United Kingdom, operating within the construction sector. The post is dated September 29, 2025, which serves as the published date for the leak since no separate compromise date is provided. The page includes a JSON-LD article block with the headline matching the victim name and a 2025-09-29 publication date, indicating the timing of the leak’s appearance. The accompanying description references travelhackingtool[.]com as the source of a free aviation data API, an element that appears unrelated to the victim but is included in the leakage text. The content signals a data-leak scenario with references to substantial data volume. The page lists two data archives available for download, accompanied by a downloads guide, and notes a data volume of 184 GB along with a revenue figure of about 6.1 million USD. Data categories such as Customer Management, Procurement & Purchasing, and Financial Reporting are mentioned in the excerpt. The page contains no images or screenshots.

In addition to the textual content, the leak page provides two data archives for download: jestacey-partner[.]zip (601 kB) and jestacey.com_listing.zip, along with a guide linked for downloads. The presence of these archives aligns with a data-exfiltration narrative common to ransomware leaks, and their filenames imply attachments containing partner information and a site listing. While the page flags a sizeable data entity (184 GB) and business metrics (e.g., revenue), there is no explicit ransom demand or encryption detail shown in the provided excerpt. A contact string appears in the text but has been redacted to protect privacy, consistent with the redaction of PII in leak-page material. The overall presentation suggests a data-leak incident rather than a straightforward encryption event.

The post date is September 29, 2025, and there is no separate compromise date indicated in the available data. This reinforces the interpretation that the public-facing element is the leak post itself rather than a contemporaneous incident timeline. For the construction sector, the exposure of data categories such as Customer Management, Procurement & Purchasing, and Financial Reporting, together with the attached data archives, highlights notable risk around sensitive commercial information and partner data. Defenders should treat this as a data-leak exposure and consider reviewing access controls, data classifications, and monitoring for any further exfiltration patterns associated with similar leak-page activity.
