A dataset containing numeric user IDs paired with what appear to be SHA-1 password hashes (40 hex characters), with some entries redacted as 'xxx'. The IDs range from low values (1410) to ~20 million, suggesting a moderately large platform. No filename, domain, or company name is available to identify the target. The format is consistent with a leaked user credentials table.
