MITRE ATT&CK

T1204.002 Malicious File T1559.002 Component Object Model

The PDF file contains embedded JavaScript and a Flash object (SWF file), both of which are commonly used to exploit vulnerabilities and deliver malicious payloads. The ClamAV detection 'Pdf.Exploit.Agent-35955' strongly indicates the presence of an exploit. The embedded JavaScript and SWF file are the likely vectors for this exploit, leading to the execution of further malicious code.

Heuristics 7

ClamAV: Pdf.Exploit.Agent-35955 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-35955
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.
RichMedia (Flash) high PDF_RICHMEDIA

PDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
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.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.

Extracted artifacts 2
