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 URLs, with the primary one being http://loaminoo.linkpc.net/1090094093096092096/Nikola-Tesla-Knows-How-to-Invent-the-Future-Blujesto-Press-Knows-Book-4-by-Fletcher-Rhoden.pdf. The document body, though heavily obfuscated, also contains references to these URLs. The purpose appears to be to drive traffic to these external links, potentially for SEO manipulation or to serve further malicious content.

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.
