MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT and PDF_JS. The critical CVE_2009_4324 heuristic suggests exploitation of a known vulnerability in PDF media handling. The embedded JavaScript, particularly the unescape() call, is likely used to deobfuscate and execute malicious code, potentially downloading a second-stage payload. The ClamAV detection further confirms its malicious nature.
