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

The PDF document contains multiple embedded URLs, with a primary focus on luring users to download game-related content. The ML classifier strongly indicates maliciousness, and the presence of external URIs suggests an attempt to redirect the user to a malicious download site. The document body text and extracted URLs point towards a scam related to in-game items for popular games like Roblox and Coin Master.
