MITRE ATT&CK

T1059.001 PowerShell T1566.001 Spearphishing Attachment T1204.002 Malicious File

This PDF file exhibits multiple high-severity heuristic firings, including PDF_JAVASCRIPT, PDF_JS, PDF_RICHMEDIA, and PDF_EVAL, strongly indicating malicious intent. The ML classifier also flagged it with high confidence. The presence of embedded JavaScript and a Flash object (GhouDiky.swf) suggests an attempt to execute code or exploit vulnerabilities. The extracted JavaScript file, javascript_obj0006_000.js, likely contains obfuscated code designed to download and execute 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.

Extracted artifacts 2

Files carved from inside the sample during analysis.
