MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF document contains multiple embedded URLs, including one pointing to 'legit-coin-master-hack-october-2021-game-hack', suggesting a lure for game-related cheats or hacks. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of external URIs and the document's deceptive content indicate an attempt to trick the user into downloading a secondary payload, likely for exploitation.
