MITRE ATT&CK

T1059.001 PowerShell T1559.002 Component Object Model Hijacking

The PDF file contains embedded JavaScript and a RichMedia (Flash) object, indicating an attempt to execute code. The presence of `eval()` calls within the JavaScript stream suggests obfuscation and dynamic code execution. The extracted artifacts, 'eYKmNyAufJyuB.swf' and 'javascript_obj0006_000.js', are likely components of the malicious payload delivery mechanism.

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.
