MITRE ATT&CK

T1566.001 Spearphishing Attachment T1027 Obfuscated Files or Information

The PDF file exhibits characteristics of malicious intent, including obfuscated object names and the presence of an embedded file. The ClamAV detection for 'Heuristics.PDF.ObfuscatedNameObject' strongly suggests malicious content. The embedded file, named 'embedded_file_obj0001.bin', is likely a secondary payload. The XFA form and embedded file heuristics further support the assessment of a malicious document designed to deliver further malware.
