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

The PDF contains an embedded URI pointing to a URL associated with game cheats and hacks, and multiple other URLs hosted on indokashcrafts.com that also reference game cheats and downloads. The ML classifier strongly flagged this PDF as malicious, and the presence of a 'download button' heuristic further supports a malicious intent to trick the user into downloading a payload. The document body, though heavily obfuscated, contains references to 'Coin Master Email Free Spins' and a URL matching the embedded URI.
