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

The PDF document contains a large number of external links, a technique often used for SEO manipulation or to redirect users to malicious sites. The document body itself contains garbled text and references to 'Battlefield bad company 2 apkpure', suggesting a lure to a potentially harmful download. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external links, reinforcing the malicious intent. No scripts were extracted from this sample.

  • 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.
