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

The ML classifier strongly indicated maliciousness, and the document body contains numerous URLs promoting free game-related items and hacks. The presence of a PDF URI heuristic further supports the likelihood that these links are intended to lead users to malicious downloads or phishing sites. No scripts were extracted from this sample.
