MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT, PDF_JS, PDF_EVAL, and PDF_UNESCAPE. The presence of eval() and unescape() calls within the JavaScript suggests obfuscation and dynamic code execution. The primary intent appears to be the execution of arbitrary code, likely to download and run a second-stage payload. Due to the obfuscation and lack of specific indicators, the family is unknown.

Heuristics 5

eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution
unescape() call high PDF_UNESCAPE

unescape() found — often used to decode shellcode in PDF JS exploits
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.
