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

The PDF document contains heuristics indicating social engineering tactics, specifically a 'ClickFix' attack that prompts the user to execute a command. It also includes embedded URLs that likely lead to malicious downloads, disguised as game hacks. The document body explicitly contains a call-to-action phrase 'CLICK HERE TO ACCESS MINECRAFT GENERATOR' and multiple URLs pointing to potentially malicious content.

Machine Learning

  • Nyx PDF Classifier malicious score 0.8068

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.
