MITRE ATT&CK

T1204 Malicious File T1204.002 Malicious File: User Execution: Malicious Attachment

The PDF file was flagged by multiple high-confidence heuristics, including ML classification and ClamAV detection, indicating it is a malicious exploit. The presence of an embedded script payload and XFA form suggests it is designed to execute malicious code upon opening. The embedded URLs are likely part of the exploit or delivery mechanism.

Heuristics 6

ClamAV: Pdf.Exploit.Dropped-93 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Dropped-93
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.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
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.
