MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF document was flagged by a machine learning classifier as malicious. It contains a large number of embedded links, forming a link farm, which is a common technique for SEO poisoning or distributing malicious content. The primary heuristic indicates a 'PDF_SEO_LINK_FARM' with 21 external links, predominantly hosted on 'xiixmcuin.linkpc.net'. While the URLs themselves are currently marked as benign, the sheer volume and structure suggest a malicious intent to redirect users to potentially harmful content.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
