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

The PDF document contains multiple links and text related to obtaining free in-game currency or cheats for popular games like Roblox and Coin Master. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests a lure to a site likely hosting a malicious payload. The document's purpose appears to be social engineering users into clicking these links, which is a common tactic for distributing malware.
