MITRE ATT&CK

T1059.001 PowerShell T1566.001 Spearphishing Attachment

The PDF file exhibits characteristics of malicious intent through obfuscated objects and the presence of an embedded file, as flagged by ClamAV. The embedded file, named 'embedded_file_obj0001.bin', is a strong indicator of a dropper or exploit delivery mechanism. The XFA form and embedded file heuristics suggest a complex attack vector designed to evade detection.
