MITRE ATT&CK

T1059.001 JavaScript/JScript T1204.002 Malicious JavaScript

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including 'PDF_JAVASCRIPT' and 'PDF_JS'. The 'PDF_U3D_CVE_RELATED' heuristic suggests exploitation of a vulnerability in Adobe Reader's 3D content parsing. The embedded JavaScript, particularly the larger 'javascript_obj0001_000.js' file, is likely responsible for executing the malicious payload. The ClamAV detection 'Heuristics.PDF.ObfuscatedNameObject' further supports the malicious nature of the file.

Heuristics 6

U3D/3D content in PDF — Adobe Reader 3D parser CVE-family indicator high CVE related PDF_U3D_CVE_RELATED
