MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript with an eval() call, indicating an attempt to execute arbitrary code. The 'PDF_LAUNCH' and 'PDF_JAVASCRIPT' heuristics further support this, suggesting the file is designed to exploit a vulnerability and run a malicious script. The script itself is obfuscated, but the presence of eval() strongly implies it's intended to download and execute a secondary payload. No specific family could be identified.

Heuristics 5

Launch action high PDF_LAUNCH

PDF contains a /Launch action with an unresolved or extension-less target — treat as potentially dangerous
eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution (matched inside decoded stream)
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.
