MITRE ATT&CK

T1557 Adversary-Controlled Chain of Trust

The PDF file was flagged by ClamAV with 'Heuristics.PDF.ObfuscatedNameObject', indicating a suspicious structure. Furthermore, a critical heuristic identified an embedded file, 'embedded_file_obj0001.bin', which is a common technique for delivering secondary malicious payloads. The XFA form heuristic also suggests a potentially complex or obfuscated document structure.
