MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple external URLs, including one that directly advertises a game hack. The presence of a 'download button' heuristic and the ML classifier's high confidence score indicate a malicious intent. The document body, though partially corrupted, contains text related to game hacks and a call to action, reinforcing the lure. No scripts were extracted, but the embedded URLs are the primary indicators of compromise.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
