MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript and a Flash object, indicated by the PDF_JAVASCRIPT, PDF_JS, and PDF_RICHMEDIA heuristics. The embedded JavaScript stream and the deobfuscated JavaScript file 'legacy_pdfkit_stage_000.js' likely contain code to execute the embedded Flash file 'TyPWoIJRMY.swf'. This chain of execution is characteristic of exploits that leverage vulnerabilities in PDF viewers to download and run further malicious content.

Heuristics 6

RichMedia (Flash) high PDF_RICHMEDIA

PDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
