MITRE ATT&CK

T1059.001 PowerShell T1204.001 Malicious Link T1204.002 Malicious File

This PDF file contains embedded JavaScript that utilizes the Collab.getIcon and Collab.collectEmailInfo functions, known to be vulnerable in CVE-2009-0927 and CVE-2007-5659 respectively. The JavaScript is obfuscated and uses an eval() call, indicating an attempt to hide malicious code execution. The primary goal appears to be exploiting these vulnerabilities to achieve arbitrary code execution.

Heuristics 7

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)
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. (matched in decompressed stream)
ClamAV: Heuristics.PDF.ObfuscatedNameObject critical CLAMAV_DETECTION
