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

The PDF document contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic. These URLs point to various book titles hosted on the 'loaminoo.linkpc.net' domain. While the extracted URLs are currently marked as benign, the sheer volume and the nature of the heuristic suggest a potential for malicious redirection or SEO abuse. No scripts were extracted from this sample. The attack pattern is inferred from the heuristic and the embedded URLs.

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.
