MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The ML classifier and ClamAV heuristic firings strongly indicate this PDF is malicious, likely due to an obfuscated object and embedded content. The 'PDF_EMBEDDED' and 'EXTRACTED_FILE_STATIC_TRIAGE' heuristics confirm the presence of an embedded file, which is a common delivery mechanism for further exploitation. The document body is heavily obfuscated and unreadable, providing no direct clues to its intent.
