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

The PDF contains an embedded URI pointing to a suspicious URL, and a machine learning classifier flagged it as malicious. The presence of a visual download button and references to popular games suggest a lure to trick users into downloading a second-stage payload. No scripts were extracted from this sample, limiting further analysis of its execution flow.
