MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document contains embedded links that lead to known malicious redirector infrastructure, specifically targeting users with lures for game hacks and currency. The document body and heuristics indicate a social engineering attempt to trick users into clicking these links, likely to download further malware or engage in phishing. No scripts were extracted from this sample, but the PDF structure itself facilitates the malicious redirection.

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.
