MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a heuristic firing for a link farm, with 23 external PDF links embedded within the document. The dominant host for these links is loaminoo.linkpc.net. While the extracted URLs are currently marked as confirmed benign, the sheer volume and structure suggest a malicious intent, likely to lead users to phishing or malware distribution sites. No scripts were extracted from this sample.

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.
