MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF file was flagged by ClamAV with 'Heuristics.PDF.ObfuscatedNameObject', indicating a suspicious structure often used to hide malicious content. Furthermore, a PDF_EMBEDDED heuristic indicates the presence of an embedded file, 'embedded_file_obj0001.bin', which is a common delivery mechanism for malware. The XFA form heuristic also suggests potential for exploitation. The document body is heavily obfuscated and does not provide direct clues to the attack's intent.
