MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF contains a large number of external links, many of which are SEO-optimized and point to pages related to game hacks and in-game currency. The ML classifier strongly flagged this PDF as malicious, and the presence of numerous external URIs suggests a link farm designed to redirect users to potentially harmful content. While no scripts were explicitly extracted, the PDF structure and embedded links are indicative of a phishing or malware distribution attempt.
