MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, as indicated by the PDF_SEO_LINK_FARM heuristic. The ML classifier and ClamAV also flagged this file as malicious. The embedded URLs likely lead to further malicious content or phishing pages, and the document body's mention of 'Pan application form' suggests a lure for financial or identity-related scams.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
