MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, identified by the PDF_JAVASCRIPT and PDF_JS heuristics. The critical CVE_2007_5659 heuristic indicates the exploitation of a known PDF vulnerability using JavaScript that is obfuscated and then deobfuscated into multiple stages. This suggests the primary purpose is to execute arbitrary code, likely downloading and running a second-stage payload. The ClamAV detection further confirms its malicious nature.
