The sample is a PDF file that utilizes an XFA form to trigger the CVE-2010-0188 exploit, targeting Adobe Reader. This exploit is known to deliver a second-stage payload. The embedded URL, while seemingly benign, is part of the XFA template structure and likely related to the exploit delivery mechanism.

PDF differential parser failed info PDF_DIFFERENTIAL_PARSE_FAILED

The cross-check parser (pdfminer.six) failed on this file: PDF differential parser failed: PSEOF. Static heuristics still ran and any of their findings above are valid; only the differential cross-check signal is missing.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
