MITRE ATT&CK
T1059.001 PowerShell

The PDF file was identified as malicious due to a critical heuristic firing for a PDF SEO link farm. It contains numerous embedded links, with the first identified URL being http://loaminoo.linkpc.net/2091092097091094/Keeper-of-Directions-by-L-K-Mitchell.pdf. The document body is heavily obfuscated and truncated, preventing a detailed analysis of its specific content or intent beyond the link farm. 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.
