T1566.001 Spearphishing Attachment
T1059.007 JavaScript
T1203 Exploitation for Client Execution
T1105 Ingress Tool Transfer
The PDF file contains embedded JavaScript that triggers a launch action for cmd.exe, which in turn attempts to execute an embedded Windows executable disguised as a PDF file named 'Paradis-rdebuts_fr.pdf'. This chain of actions, combined with the ML classifier and ClamAV detections, strongly indicates a malicious intent to deliver a second-stage payload. The presence of external URLs suggests potential C2 communication or further payload download.

Heuristics 15
-
Adobe Reader Launch action command execution critical CVE exact CVE_2010_1240PDF 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_LAUNCHPDF 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_PAYLOADPDF 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_COMMANDPDF /Launch action specifies an executable target with parameters '/Q /C %HOMEDRIVE%&cd %HOMEPATH%&(if exist "Desktop\\Paradis-rdebuts_fr.pdf" (cd "Desktop"' — references a known-dangerous executable (cmd, PowerShell, etc.).
-
Embedded attachment masquerades: declared document, content is windows-executable critical PDF_EMBEDDED_FILESPEC_CONTENT_MISMATCHAn /EmbeddedFile attachment's declared filename extension or /Subtype MIME type contradicts the magic bytes of its decompressed content. The attachment is declared as a benign document or image but the bytes are an executable or executable-bearing archive. This is a deliberate deception used to hide droppers in PDF attachments and is a generic indicator of embed-and-drop weaponisation, independent of any specific CVE.
-
ClamAV: Pdf.Tool.Agent-1388586 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Tool.Agent-1388586
-
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAVClamAV 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.
-
/Launch action paired with attachment-dropping JS API high PDF_LAUNCH_PLUS_DROPPER_JSPDF combines a /Launch action with a JavaScript API call that writes or opens an attached/external resource — the canonical shape of the CVE-2010-1240 /Launch + exportDataObject family. Benign PDFs do not pair these surfaces; the combination indicates a drop-and-execute chain regardless of the specific JS API knobs or /Launch target.
-
Clickable PDF combines external action with parser-evasion structure high PDF_ACTION_PARSER_EVASIONPDF has an external clickable URI together with object graph or xref structures that make parsers disagree, such as divergent duplicate objects, parser divergence, or xref offset mismatch. That combination is stronger than a plain link: the document is both an outward-action carrier and a parser-confusion/evasion sample.
-
Callback phishing phone lure medium SE_CALLBACK_LUREDocument asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) documents that carry no urgency or charge/dispute escalation.
-
JavaScript action low PDF_JAVASCRIPTPDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
-
Embedded JS stream low PDF_JSPDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
-
Embedded file low PDF_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
External URI info PDF_URIPDF contains an external URL action
-
Embedded URL info EMBEDDED_URLOne 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.URL http://www.insightful.com/products/splus/default.asp
