MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

The PDF contains embedded JavaScript and a RichMedia Flash object that exploits CVE-2010-1297. This exploit is designed to execute arbitrary code, likely by loading and running the embedded WpuVlEGnF.swf file. The JavaScript appears to be obfuscated but is responsible for triggering the exploit. The embedded SWF file is a strong indicator of a multi-stage attack.

Adobe Flash authplay SWF exploit in PDF — CVE-2010-1297 critical CVE likely CVE_2010_1297_FLASH_RICHMEDIA

PDF combines RichMedia Flash activation, a crafted SWF with ActionScript prototype/AVM-era markers or the AES-PHP/authplay variant markers, and PDF-side shellcode heap-spray staging. This is the static delivery shape associated with CVE-2010-1297 in Adobe Reader's bundled authplay.dll.
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
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.
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.
