MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs and a document body that attempts to lure users with offers of free followers and game currency. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests a download or redirection attempt. Although no scripts were explicitly extracted, the PDF structure and embedded URIs indicate a likely attempt to deliver a second-stage payload.
