MITRE ATT&CK

T1204.002 Malicious File T1059.001 JavaScript T1059.007 JavaScript

The PDF file contains embedded JavaScript and U3D content, triggering heuristics related to CVE-2007-5659 and PDF JavaScript execution. The deobfuscated JavaScript, 'legacy_pdfkit_stage_000.js', likely downloads and executes a second-stage payload. The presence of U3D content further indicates a potential exploit targeting Adobe Reader's 3D parsing capabilities.

Heuristics 5

Collab.collectEmailInfo — CVE-2007-5659 critical CVE exact CVE_2007_5659

PDF JavaScript calls Collab.collectEmailInfo — CVE-2007-5659 is a buffer overflow in Adobe Reader triggered by a long argument or heap-sprayed message field passed to Collab.collectEmailInfo(). Part of a series of Acrobat JS API exploits. (identified after JavaScript deobfuscation)
U3D/3D content in PDF — Adobe Reader 3D parser CVE-family indicator high CVE related PDF_U3D_CVE_RELATED

PDF contains U3D (Universal 3D) or 3D annotation content — CVE-2011-2462 and CVE-2009-3953 are critical vulnerabilities in Adobe Reader's U3D processing that allow arbitrary code execution. U3D content in PDFs is extremely rare in normal documents.
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
