Document Integrity
We independently verify every EFTA document released by the DOJ using SHA-256 cryptographic hashes. This dashboard tracks document availability, detects tampering, and logs all changes to the case files.
Dataset 9 — Significant Anomalies Detected
Dataset 9 (DS9) has the most significant integrity issues of any EFTA release. Independent monitoring by beak2825/epstein-files-archive documented that 928 documents were deleted and 0 documents were modified on DOJ servers after their initial release.
These changes were detected by tracking HTTP responses from DOJ servers over time. Files that previously returned 200 OK began returning 404 Not Found, and others showed different ETags and Last-Modified headers indicating content changes. Some of these changes occurred shortly after media coverage of the released documents.

Methodology
Hash Sources
SHA-256 hashes are sourced from rodrigopolo/epstein-doj-library-sha256, which computed hashes for ~1.35 million files across all 12 EFTA datasets at the time of release.
Deletion & Modification Tracking
Document availability changes are tracked by beak2825/epstein-files-archive, which monitors DOJ server HTTP responses over time. Deletions are detected when previously available files return 404/410 status codes. Modifications are detected via ETag and Last-Modified header changes.
Verification Process
- Verified: File was fetched from DOJ and its SHA-256 hash matches the original release hash.
- Pending: Hash is stored but the file has not yet been re-downloaded for verification.
- Mismatch: File was fetched but its SHA-256 hash differs from the original, indicating content was changed.
- Unavailable: File returns 404/410 from DOJ servers — it has been deleted.
Independent Verification
You can independently verify any document hash using standard tools:
sha256sum EFTA00351709.pdf
Compare the output against the hash shown on each document's page. All hashes and change logs are available through our public API.
