MITRE ATT&CK

T1059.001 PowerShell T1204.001 Malicious Link

The PDF file contains multiple critical heuristic firings indicating exploitation of CVE-2009-4324, CVE-2009-0927, and CVE-2007-5659. These exploits leverage embedded JavaScript to likely download and execute a secondary payload. The presence of deobfuscated JavaScript files further supports this attack vector. The file's purpose is to exploit these vulnerabilities for further malicious activity.

Heuristics 6
