MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The sample is a PDF file flagged by multiple heuristics, including a critical ClamAV detection for obfuscated objects and an ML classifier indicating high maliciousness. An embedded file was also extracted, suggesting it acts as a dropper for a secondary payload. The document body is heavily obfuscated and unreadable, providing no direct clues about the lure.
