MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The file is a PDF containing JavaScript, which is often used to exploit vulnerabilities. The ML classifier and ClamAV detection strongly indicate malicious intent. The presence of PDF_JAVASCRIPT, PDF_JS, PDF_FILTER_HEX, and PDF_FILTER_85 heuristics further supports the exploitation of PDF vulnerabilities. The specific exploit used is identified by ClamAV as Pdf.Exploit.Agent-36178.

Heuristics 6

ClamAV: Pdf.Exploit.Agent-36178 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-36178
ASCIIHexDecode filter (with exploit indicators) medium PDF_FILTER_HEX

Hex-encoding filter present alongside exploit delivery indicators — often used to hide payload or shellcode bytes
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.
String.fromCharCode low PDF_FROMCHARCODE

String.fromCharCode found — used to construct payload strings dynamically. Common in benign JavaScript libraries for codepoint manipulation, so this alone is informational; weaponised use is also caught by the dedicated fromCharCode-stage and exploit-shape rules. (matched inside decoded stream)
ASCII85Decode filter (with exploit indicators) low PDF_FILTER_85

ASCII85 encoding filter present alongside exploit delivery indicators — uncommon outside of obfuscation
