MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file was identified as malicious due to a critical heuristic firing for a link farm. It contains 32 embedded external links, all pointing to URLs hosted on 'xiixmcuin.linkpc.net'. While the linked PDFs themselves are currently classified as benign, the sheer volume and nature of these links suggest a malicious intent to direct users to potentially compromised or malicious content, possibly as part of a phishing or SEO poisoning campaign.

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.
