MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF file contains an embedded object, indicated by the PDF_EMBEDDED heuristic and the presence of an 'embedded_file_obj0001.bin' artifact. ClamAV also flagged this file as Heuristics.PDF.ObfuscatedNameObject, suggesting malicious obfuscation techniques are in use. The XFA form heuristic might indicate a method for triggering embedded content. The primary attack pattern is likely the exploitation of a PDF viewer vulnerability to execute the embedded file.
