MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF document contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. The document body also contains these URLs, suggesting a lure to click through to potentially malicious content hosted on loaminoo.linkpc.net. No scripts were extracted from this sample, and the document body content is heavily obfuscated, limiting further analysis of the exact payload.

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.
