MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure related to free game currency and includes multiple embedded URLs pointing to potentially malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button heuristic further supports a malicious intent to trick users into downloading a payload. No scripts were extracted, but the document's structure and embedded URLs suggest it is designed to facilitate the download of a second-stage malicious file.
