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

The PDF file was flagged by a machine learning classifier as malicious and contains a large number of embedded links. These links point to external PDF files hosted on loaminoo.linkpc.net, suggesting a link farm or SEO manipulation tactic. No scripts were extracted, and the document body was unreadable, but the presence of numerous external links is a strong indicator of malicious intent, likely to direct users to potentially harmful content or phishing sites.

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.
