MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The document presents itself as a download for 'Pokemon Go' and contains a prominent external URI pointing to a suspicious domain. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related heuristics further supports a malicious intent. The document body, though heavily obfuscated, contains text related to game downloads and a URL that likely leads to a second-stage payload.
