MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded links that point to known malicious redirector infrastructure, specifically targeting game-related lures like 'minecraft-1.15-2-hacks'. The document body, though heavily obfuscated, also contains URLs that appear to be part of a phishing or malware distribution scheme. The presence of a visual download button heuristic further supports the malicious intent of directing users to external, potentially harmful content.

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.
