MITRE ATT&CK

T1204.002 Malicious File: User Execution T1566.002 Phishing: Spearphishing Attachment T1059.001 Command and Scripting Interpreter: PowerShell

The PDF file contains an XFA form and an embedded script payload, as indicated by the PDF_XFA and PDF_EMBEDDED_SCRIPT_PAYLOAD heuristics. ClamAV detections (Pdf.Exploit.Agent-36789 and Pdf.Exploit.Agent-36809) confirm its malicious nature. The embedded script is likely responsible for downloading and executing a second-stage payload, a common technique for PDF-based malware delivery. The embedded URL was not directly actionable due to encoding.

Heuristics 5

ClamAV: Pdf.Exploit.Agent-36789 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-36789
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.
Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD

PDF 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.
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
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.
