T1204.002 Malicious File: User Execution: Malicious Attachment
T1566.002 Phishing: Spearphishing Attachment
T1059.001 Command and Scripting Interpreter: PowerShell
The PDF file was detected by ClamAV as Pdf.Exploit.Dropped-78, indicating it contains exploit code. A critical heuristic firing confirms an embedded script payload within a PDF stream. The presence of an embedded file object further supports the malicious nature of the document. The exact intent of the embedded script is not fully discernible due to obfuscation, but its presence in conjunction with exploit detection strongly suggests it's designed to download and execute a secondary payload.

ClamAV: Pdf.Exploit.Dropped-78 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Exploit.Dropped-78
-
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
-
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://ns.adobe.com/xdp/
