MITRE ATT&CK

T1204.002 Malicious File T1059.003 Windows Command Shell T1105 Ingress Tool Transfer

The PDF contains embedded JavaScript and a critical PDF_LAUNCH heuristic firing indicating a launch action targeting cmd.exe. This action is part of a chain exploiting CVE-2010-1240 to execute an embedded PE payload. The embedded executable was detected by ClamAV as Win.Trojan.Rozena-131, and the PDF itself was flagged as Pdf.Exploit.Agent-13433. The primary attack vector involves tricking the user into opening the PDF, which then executes the embedded malicious executable.

Heuristics 10

Adobe Reader Launch action command execution critical CVE exact CVE_2010_1240

PDF uses the Adobe Reader/Acrobat Launch action pattern associated with CVE-2010-1240: cmd.exe is invoked with attacker-controlled parameters, paired with an embedded/exported payload.
Launch action critical PDF_LAUNCH

PDF contains a /Launch action whose target is an executable, URL, or UNC path — can start an external application
Embedded Windows executable payload in PDF stream critical PDF_EMBEDDED_PE_PAYLOAD

PDF stream bytes contain an embedded Windows executable with a verified PE header. Exploit chains often hide droppers inside ordinary streams rather than standard /EmbeddedFile attachments.
/Launch action target: cmd.exe critical PDF_LAUNCH_COMMAND

PDF /Launch action specifies an executable target with parameters '/Q /C (if exist "%HOMEPATH%\\My Documents\\NASCAR.pdf" (cd "%HOMEPATH%\\My Documents"' — references a known-dangerous executable (cmd, PowerShell, etc.).
ClamAV: Pdf.Exploit.Agent-13433 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-13433
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.
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
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
