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

The ML classifier strongly indicates maliciousness, and the document body contains a URL designed to trick users into downloading a payload. The document's content and embedded URLs suggest a lure for game-related cheats or hacks, likely leading to malware. No scripts were extracted from this sample.

  • External URI info PDF_URI
    PDF contains an external URL action
