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

The PDF document contains a lure for a fake download, specifically mentioning 'Minecraft Apk Download Free'. It also includes a heuristic indicating a 'ClickFix' social engineering attack, instructing the user to press Win+R or paste a command into a terminal to bypass macro restrictions. The embedded URL points to a suspicious domain, likely serving as the download source for a malicious payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9871

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.
