MITRE ATT&CK
T1204.002 Malicious File

The PDF file contains obfuscated objects and an embedded file, as indicated by the ClamAV heuristic 'Heuristics.PDF.ObfuscatedNameObject' and the 'PDF_EMBEDDED' firing. The presence of an embedded file suggests an attempt to deliver a secondary payload. The document body is heavily obfuscated and unreadable, providing no further context on the lure.
