MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links, many of which are hosted on domains that appear to be part of a link farm. The document body, though heavily obfuscated, contains references to a 'Chevrolet epica service manual' and the wkhtmltopdf tool, suggesting a lure to disguise the malicious intent. The primary heuristic firing indicates a 'PDF_SEO_LINK_FARM', suggesting the document's purpose is to drive traffic to a network of related sites, likely for SEO manipulation or to host further malicious content.

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.
