MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF sample contains embedded JavaScript that is heavily obfuscated and utilizes unescape calls, indicating an attempt to hide malicious code. Heuristics and ClamAV detection strongly suggest this is a PDF exploit designed to execute arbitrary code. The ML classifier also flagged it with high confidence. The primary function appears to be the execution of this script, likely to download and run a secondary payload.

Heuristics 6

PDF JavaScript exploit cluster critical PDF_JS_EXPLOIT_CLUSTER

PDF combines an executable JavaScript/action surface with exploit staging indicators such as eval/unescape/fromCharCode, XFA script content, or a related CVE pattern. Benign form JavaScript remains low-severity, but this correlated cluster is high-confidence malicious behavior.
ClamAV: Pdf.Exploit.Agent-23468 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-23468
unescape() call high PDF_UNESCAPE

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