MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual download lure, attempting to trick users into downloading malicious content by offering free game accounts and in-game currency. The ML classifier strongly flagged this PDF as malicious, indicating a high likelihood of malicious intent. While no scripts were explicitly extracted, the presence of external URIs and the lure suggest a phishing or downloader attack pattern.

Heuristics 4

QR-code redirect lure medium SE_QR_LURE

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
External URI info PDF_URI

PDF contains an external URL action
Embedded URL info EMBEDDED_URL
