MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic. These URLs point to various PDF files hosted on the same domain, suggesting a link farm or a distribution mechanism for potentially malicious content. No scripts were extracted from this sample. The primary attack pattern appears to be the distribution of links rather than direct execution of malicious code within the PDF itself.

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.
