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

The document exhibits social engineering tactics, specifically a 'ClickFix' lure, by instructing the user to interact with a link to download a file. The embedded URL and numerous other URLs point to sites offering game-related cheats or hacks, suggesting the document's purpose is to trick users into downloading potentially unwanted or malicious software. No scripts were extracted, but the presence of embedded URLs and the social engineering heuristic strongly indicate a malicious intent to deliver a payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9432

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.
