MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains an external URI pointing to a lure for free in-game currency, strongly suggesting a phishing or social engineering attempt. The ML classifier also flagged this PDF as malicious with high confidence. The document body, though partially corrupted, contains references to the same lure and embedded URLs, reinforcing the malicious intent.
