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

The PDF contains embedded links and a visual download button, directing users to external sites that appear to offer game-related hacks and free items. The primary link, https://netcdn.xyz/app/479516143/minecraft-1.15-2-hacks-game-hack, is flagged as a malicious redirector. This suggests the document is designed to trick users into downloading malware or visiting malicious sites under the guise of obtaining game cheats or in-game currency.
