MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

This PDF document contains an embedded Adobe Flash exploit (CVE-2010-1297) targeting a vulnerability in Flash Player. The exploit is designed to execute arbitrary code, likely downloading and running a secondary payload. The embedded JavaScript further supports this by containing obfuscated code that likely facilitates the exploit execution and payload delivery.

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.
Hex-obfuscated scripting name object critical PDF_OBFUSCATED_NAME_OBJECT

A PDF name object that drives script execution (/JavaScript or /JS) is written with #XX hex escapes to hide it from string-based scanners — e.g. /J#61v#61S#63r#69p#74 decoding to /JavaScript. Legitimate PDF producers always write these names literally; hex-encoding an executable name is a deliberate evasion used by exploit-kit and dropper PDFs.
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.
