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

The PDF document contains multiple embedded URLs and a prominent external URI pointing to a download site, disguised as a guide for obtaining free items in popular games. The ML classifier strongly flagged this PDF as malicious, indicating a high likelihood of it serving a malicious payload or redirecting to a phishing site. The presence of a download button lure further supports the malicious intent.
