MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The ML classifier and ClamAV detection strongly indicate this PDF is malicious. The 'PDF_EMBEDDED' heuristic and the presence of an 'embedded_file_obj0001.bin' artifact suggest that the document is designed to drop and execute a secondary payload. The document body is heavily obfuscated, preventing a more detailed analysis of its specific lure.
