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

The PDF document contains a deceptive title and a large number of embedded links to external PDF files, indicating a link farm or redirection strategy. The primary URL http://74-123-77-90.mgwnet.com/uploads/1/3/0/7/130740368/130740368.html#descargar+la+cancion+de+kevinho+tumbalatum appears to be a lure for downloading content. The numerous other PDF links suggest a broad distribution or obfuscation tactic. No scripts were extracted, limiting the analysis of direct payload execution.

Heuristics 3

  • 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.
  • 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.
