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

The PDF was flagged by a critical heuristic for containing a mass external link farm, with 21 links pointing to the dominant host 'loaminoo.linkpc.net'. While the ML classifier also flagged it as malicious, the specific URLs extracted were classified as benign. The attack pattern is likely a form of SEO abuse or a lure to a potentially malicious site, rather than direct malware delivery via the PDF itself.

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.
