MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains a large number of external links, many of which point to other PDF files hosted on different domains. This suggests a link farm or SEO poisoning tactic, likely intended to drive traffic to these sites. The document body contains garbled text and embedded URLs, reinforcing the malicious intent of directing users to external, potentially malicious, content. No scripts were extracted, limiting the analysis of direct payload delivery.

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.
