T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious File

The PDF document contains embedded URLs and text that lure the user into downloading game cheats. The ML classifier strongly indicates maliciousness, and the presence of an external URI points to a download attempt. The document's content and heuristics suggest it is a phishing lure for potentially unwanted or malicious software.
