MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains numerous external links, many of which point to PDF files hosted on various domains, suggesting a link farm or redirection mechanism. The 'SE_CALLBACK_LURE' heuristic indicates the document's content is designed to trick users into calling a phone number, consistent with callback phishing or tech-support scams. The primary URL found in the document body, 'http://74-123-72-180.mgwnet.com/uploads/1/3/0/4/130435611/130435611.html#asset+management+reports+example', is presented as an asset management report, further supporting the lure tactic.

Heuristics 4

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
