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 'EXTRACTED_FILE_STATIC_TRIAGE' heuristic flags suspicious elements like hex escape obfuscation and script obfuscation within the extracted 'javascript_obj0013_001.js' file. ClamAV also detected this as 'Pdf.Exploit.Agent-36014'. The embedded JavaScript is likely responsible for executing malicious code, potentially downloading and running a second-stage payload, which aligns with the critical ClamAV detection.
