T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs that promise free in-game currency or hacks, indicating a phishing or scam attempt. The ML classifier also flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URLs and the document's theme suggest it is designed to redirect users to malicious sites for downloading unwanted software or engaging in fraudulent activities.
