T1204.002 Malicious File
T1566.002 Spearphishing Attachment
The file is identified as a malicious PDF by ClamAV and an ML classifier, indicating it likely contains an exploit. The presence of embedded script payloads and embedded files further supports this assessment. While no specific script content was readable, the overall structure and heuristic firings strongly suggest it's a dropper or exploit delivery mechanism.
