MITRE ATT&CK

T1566.001 Spearphishing Attachment T1027 Obfuscated Files or Information

The PDF file exhibits characteristics of malicious intent through its obfuscated object names and the presence of an embedded file. The ClamAV detection for 'Heuristics.PDF.ObfuscatedNameObject' strongly indicates a deliberate attempt to conceal malicious content. The embedded file, named 'embedded_file_obj0001.bin', is likely the payload or a component thereof. The XFA form and general PDF obfuscation further support the conclusion that this document is part of a malicious delivery chain.
