MITRE ATT&CK
T1566.001 Phishing: Spearphishing Attachment T1059.001 Command and Scripting Interpreter: PowerShell

The PDF document contains a large number of embedded links, identified as a "PDF_SEO_LINK_FARM" heuristic. These links point to various PDF files hosted on the same domain, suggesting a tactic to drive traffic or distribute content through a link farm. While the document body is heavily obfuscated and unreadable, the presence of numerous external links is the primary indicator of malicious intent. 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.
