MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that strongly suggest a lure for free in-game currency or items, a common social engineering tactic. The ML classifier also flagged the PDF as malicious with high confidence. The presence of an external URI points to a potential download or redirection to a malicious site.
