MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual download button lure, suggesting an attempt to trick the user into downloading a payload. The ML classifier also flagged the document as malicious. While no scripts were explicitly extracted, the presence of external links and the overall structure indicate a likely attempt to deliver a second-stage malicious file, possibly related to game exploits or cheats.

  • External URI info PDF_URI
    PDF contains an external URL action
