MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document body contains numerous URLs related to game hacks and free currency. The presence of embedded URIs and the overall theme suggest a phishing or malware distribution attempt, likely via spearphishing attachment. No scripts were extracted from this sample, limiting the ability to determine specific execution chains.

  • External URI info PDF_URI
    PDF contains an external URL action
