MITRE ATT&CK
T1566.001 Phishing:Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of embedded links to external PDF files, hosted on the domain loaminoo.linkpc.net. This is indicative of a link farm or SEO poisoning attack. While the individual linked PDFs are marked as benign, the sheer volume and suspicious domain suggest an attempt to manipulate search results or distribute potentially malicious content indirectly. 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.
