MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded links that redirect to known malicious infrastructure, specifically a URL related to 'coin master free spins game hack'. The presence of a visual download button and the ML classifier's high confidence score further support its malicious nature. The document body and embedded URLs suggest a lure for free in-game currency or items, a common phishing tactic.

  • 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
