MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a significant number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. The primary link, http://peacevine.net/uploads/1/3/0/3/130323115/130323115.html#brinks+timers+instructions+42-1006, suggests a lure related to 'Brinks timers instructions'. The extensive link farm indicates a potential attempt to manipulate search engine results or redirect users to malicious content hosted across multiple domains.

  • 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.
