MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs and a prominent link disguised as a download button, all pointing to websites offering free in-game items. The ML classifier also flagged the PDF as malicious. The presence of these links suggests an attempt to redirect the user to a malicious site, likely for phishing or to download a secondary payload.
