MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded links to external PDF documents, a technique often used for SEO poisoning or to distribute malicious content. The dominant host for these links is loaminoo.linkpc.net, which is flagged as suspicious. While no scripts were extracted, the heuristic 'PDF_SEO_LINK_FARM' indicates a deliberate attempt to direct users to a large collection of external resources, likely for malicious purposes such as phishing or malware distribution.

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.
