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

The PDF document contains multiple embedded URLs and references to downloading hacks for popular games like Coin Master and Roblox, indicating a lure for potentially unwanted or malicious software. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect users to download content. The document's content and embedded links suggest a social engineering tactic to trick users into downloading a payload.
