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

The PDF document contains numerous embedded URLs and a prominent external URI pointing to sites offering game cheats and currency, strongly suggesting a phishing or malware distribution lure. The ML classifier also flagged this PDF as malicious with high confidence. No scripts were extracted, but the presence of download-oriented lures and external links indicates an attempt to trick the user into downloading a second-stage payload.
