MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded links that redirect to URLs hosting game hacks and cheats, indicating a social engineering lure to download potentially unwanted or malicious software. The ML classifier strongly flagged this PDF as malicious, and the presence of a redirector link further supports this assessment. No scripts were extracted, but the document body and heuristics point to a phishing attempt.

Heuristics 3

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
