The PDF document contains a lure for an advance-fee scam, specifically mentioning lottery winnings and parcel delivery requirements. It embeds numerous external links, many pointing to PDF files, suggesting a link farm designed to host scam content. The primary embedded URL, http://hostmaster.kidwellybowls.com/uploads/1/3/0/6/130604312/130604312.html#http%253A%252F%252Feasymacsupport.com%252Fuploads%252F1%252F2%252F9%252F0%252F129099120%252F129099120.html%253Fsolidworks+2013+bible+pdf, likely leads to further scam content.

Heuristics 4

  • 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.
  • External URI info PDF_URI
    PDF contains an external URL action
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
  • 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.
