MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files, many of which are hosted on the dynamic DNS domain 'loaminoo.linkpc.net'. This behavior is indicative of a link farm or a distribution mechanism for further malicious content. While no scripts were explicitly extracted, the PDF structure and the heuristic firings suggest an attempt to manipulate search engine results or direct users to potentially harmful resources.

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.
