MITRE ATT&CK

T1204.002 Malicious File Execution: Malicious File T1059.001 Command and Scripting Interpreter: JavaScript

The PDF file contains embedded JavaScript and triggers a critical heuristic for CVE-2009-0927 (Collab.getIcon). This indicates the document is designed to exploit this vulnerability to execute arbitrary code. The embedded JavaScript stream, identified as 'javascript_obj0006_000.js', is likely responsible for downloading and executing a secondary payload. The ClamAV detection further confirms its malicious nature.

Heuristics 6

Collab.getIcon — CVE-2009-0927 critical CVE exact CVE_2009_0927

PDF JavaScript calls Collab.getIcon — CVE-2009-0927 is a stack buffer overflow in Adobe Reader triggered by Collab.getIcon() with a crafted argument. Allows arbitrary code execution. (matched in decompressed stream)
ClamAV: Heuristics.PDF.ObfuscatedNameObject critical CLAMAV_DETECTION

ClamAV detected this file as malware: Heuristics.PDF.ObfuscatedNameObject
unescape() call high PDF_UNESCAPE

unescape() found — often used to decode shellcode in PDF JS exploits (matched inside decoded stream)
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.
