MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF document contains numerous embedded URLs that are disguised as links to free in-game currency and accounts for popular games. The ML classifier flagged this PDF as malicious, and the presence of these lures suggests a phishing or scam attempt. While no scripts were explicitly extracted, the embedded URLs are the primary indicators of malicious intent, likely directing users to fraudulent websites.
