MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF was flagged by a machine learning classifier and contains a large number of external links, characteristic of a link farm. The embedded URLs point to what appear to be academic papers, likely a lure to disguise the malicious intent. No scripts were extracted, and the document body was heavily obfuscated, preventing further analysis of the specific lure.

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.
