MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.001 User Execution: Malicious Link

The PDF contains embedded links and text that mimic a download prompt for game-related cheats, such as 'Minecraft Hacks' and 'CLICK HERE TO ACCESS MINECRAFT GENERATOR'. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' confirms that the primary embedded URL leads to known malicious infrastructure. The presence of a 'SE_DOWNLOAD_BUTTON' heuristic further supports the social engineering aspect of this attack.

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.
