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

The PDF contains multiple external links, including one identified as a potential malicious URI, that lead to websites offering game hacks and cheats. The presence of a visual download button heuristic further supports the conclusion that this document is designed to trick users into downloading malicious content. No scripts were extracted, but the overall structure and linked content suggest a social engineering attempt to deliver a payload.
