MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The file is a PDF document flagged by multiple heuristics, including a critical ClamAV detection for obfuscated objects and an ML classifier indicating high maliciousness. The PDF contains an embedded file, suggesting it's a dropper or exploit document. The document body is heavily obfuscated and unreadable, further supporting a malicious intent. The primary attack pattern involves exploiting PDF vulnerabilities to execute a secondary payload.
