T1059.001 PowerShell

The PDF file contains a large number of embedded URLs pointing to external PDF documents hosted on the dynamic DNS domain 'xiixmcuin.linkpc.net'. This technique is often used for SEO poisoning or to distribute malicious content indirectly. While the extracted URLs themselves are currently marked as benign, the sheer volume and the nature of the hosting domain suggest a malicious intent to drive traffic or potentially serve further malicious content. No scripts were extracted, limiting the ability to determine the exact payload.

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.
