MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains numerous external links, with a critical heuristic identifying it as a link farm designed to distribute other malicious PDFs. One prominent malicious URL, http://seachtop.com/unpaid/astrometry/dassler/..., was extracted and flagged. The document body is heavily obfuscated and unreadable, providing no further context on its specific lure.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
