MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF file contains an embedded binary artifact, indicated by the PDF_EMBEDDED heuristic and the 'embedded_file_obj0001.bin' extracted file. ClamAV detected this as malware due to an obfuscated object name. The presence of an embedded file strongly suggests an attempt to deliver a secondary payload, likely executed when the embedded file is opened.
