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

The PDF file exhibits characteristics of a link farm, with numerous embedded URLs pointing to external resources. The heuristic 'PDF_SEO_LINK_FARM' indicates a high volume of links, suggesting an attempt to lure users to potentially malicious sites. The document body itself is heavily obfuscated and does not provide clear textual content, reinforcing the reliance on the link structure for the attack. No scripts were extracted from this sample.

Heuristics 2

  • 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.
