MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF document contains numerous embedded URLs and a document body that explicitly promises ways to 'hack' or get free currency for games like Roblox and Coin Master. The presence of a download button lure and a high-confidence ML classifier firing further support its malicious nature. The primary IOC is the external URI pointing to a potential application download.
