MITRE ATT&CK

T1204.002 User Execution: Malicious File T1059.003 Command and Scripting Interpreter: Windows Command Shell T1105 Ingress Tool Transfer T1566.001 Phishing: Spearphishing Attachment

The PDF file contains embedded JavaScript and a launch action that targets cmd.exe. This chain of actions, identified by CVE_2010_1240, is designed to execute an embedded PE payload. The embedded executable was detected by ClamAV as Win.Trojan.Swrort-5710536-0, indicating it's a known trojan. The overall attack pattern suggests a malicious document used to deliver a secondary payload.

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 %HOMEDRIVE%&cd %HOMEPATH%&(if exist "Desktop\\output.pdf" (cd "Desktop"' — references a known-dangerous executable (cmd, PowerShell, etc.).
ClamAV: Pdf.Tool.Agent-1388586 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Tool.Agent-1388586
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.
