MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document presents itself as a Minecraft X-ray hack generator, with a clear call to action to download the "generator" from the URL http://netcdn.tw/app/479516143/minecraft-xray-hack-game-hack. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs indicates a likely attempt to download a second-stage payload. No scripts were extracted from this sample, but the overall lure and external URL are highly suspicious.
