MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs that are designed to trick the user into downloading other files, likely malware. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a visual download lure further supports this. The document body and embedded links suggest a scam related to in-game currency or items.
