MITRE ATT&CK

T1204.002 Malicious File: Malicious File

The PDF file contains embedded JavaScript, indicated by multiple heuristic firings including PDF_JAVASCRIPT and PDF_JS. ClamAV detection (Pdf.Exploit.Agent-36175) confirms its malicious nature, likely exploiting a PDF vulnerability to run the embedded script. The script itself is the primary IOC, as it is the mechanism for exploitation.

Heuristics 5

ClamAV: Pdf.Exploit.Agent-36175 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-36175
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
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.
