T1204.002 Malicious File
The PDF file contains obfuscated JavaScript, indicated by the PDF_JAVASCRIPT, PDF_JS, and PDF_AA heuristics. ClamAV also flagged it as Heuristics.PDF.ObfuscatedNameObject. The presence of JavaScript suggests an attempt to execute malicious code upon opening the PDF, likely leading to further stages of infection. However, the exact nature of the payload could not be determined due to obfuscation.

Additional-actions dictionary low PDF_AAPDF defines /AA (Additional Actions) that references an executable action (JS/JavaScript/Launch/SubmitForm) — can auto-trigger on document or widget events. Form-field calc/format/validate/keystroke handlers in legitimate interactive forms commonly fire this, so it is reported as a low-weight signal; weaponised auto-execution is flagged by stronger rules (PDF_OPENACTION, encrypted-with-JS, etc.)
