T1566.001 Spearphishing Attachment T1027 Obfuscated Files or Information

The PDF file was flagged by multiple heuristics, including ML classification and ClamAV detection for obfuscated objects. The presence of an embedded file, named 'embedded_file_obj0001.bin', further suggests malicious intent. The document body itself is heavily obfuscated and unreadable, reinforcing the conclusion that the file is designed to hide its true purpose.
