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

The PDF document contains embedded URLs and text that mimic a download lure for a "Minecraft" game hack. The 'SE_CLICKFIX' heuristic indicates the document likely instructs the user to execute a command, a common social engineering tactic to bypass security measures. The presence of multiple suspicious URLs suggests the document is designed to redirect users to malicious sites for further payload delivery.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9447

Heuristics 4

  • ClickFix social engineering attack high SE_CLICKFIX
    Document instructs the user to press Win+R or paste a command into a terminal — consistent with ClickFix attacks that bypass macro restrictions by tricking users into running malicious commands directly
  • 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
  • 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.
