T1204 Malicious File
T1204.002 Malicious File: User Execution: Malicious Attachment
The critical ClamAV detection 'Pdf.Exploit.Dropped-156969-1' strongly indicates this PDF is designed to exploit a vulnerability. The presence of an embedded script payload and an embedded file further supports this, suggesting the PDF acts as a dropper for a secondary malicious artifact. The document body content is largely obfuscated and does not provide clear user-facing lures.
Heuristics 5
-
ClamAV: Pdf.Exploit.Dropped-156969-1 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Exploit.Dropped-156969-1
-
Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOADPDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
-
Embedded file low PDF_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
