MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of external links, identified as a link farm, with the ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly indicating a phishing or malware distribution purpose. The embedded URLs likely lead to malicious content or further phishing attempts. The document body's mention of 'cheat codes and mods' is likely a lure to encourage clicking the malicious links.
