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

The PDF document contains a large number of external links, a technique often used to create link farms for SEO manipulation or to host malicious content. The document body, though partially corrupted, suggests a lure related to a 'vehicle safety inspection checklist'. The primary heuristic indicates a 'PDF_SEO_LINK_FARM' with 30 external PDF links, suggesting the document's purpose is to redirect users to a network of malicious PDF files hosted on various domains. No scripts were extracted from this sample.

Heuristics 3

  • 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
  • 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.
