MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

This PDF file contains embedded JavaScript and exploits multiple known vulnerabilities including CVE-2009-4324, CVE-2009-0927, CVE-2007-5659, and CVE-2008-2992. The heuristics indicate that the PDF launcher concatenates and evaluates strings derived from the info fields, a common technique for exploiting these CVEs. The embedded JavaScript, specifically 'info_stride_js_000.js', is likely responsible for the malicious payload delivery. The ClamAV detection further supports the malicious nature of an extracted artifact.

Heuristics 7
