MITRE ATT&CK

T1553.005 Mark-of-the-Web Bypass

The PDF file contains an embedded artifact, indicated by the PDF_EMBEDDED heuristic and the presence of 'embedded_file_obj0001.bin'. ClamAV also flagged this as Heuristics.PDF.ObfuscatedNameObject, suggesting malicious intent. The embedded file is the primary indicator of a malicious payload delivery. The document body is heavily obfuscated and unreadable, providing no further context on the lure.
