MITRE ATT&CK

T1204.002 Malicious File: User Execution: Malicious Attachment T1566.002 Phishing: Spearphishing Attachment

The sample is a PDF file identified as malicious by ClamAV with multiple critical detections related to embedded script payloads and exploits. The presence of an XFA form suggests a technique commonly used to embed and execute malicious content within PDFs. The embedded script payload, though not directly analyzed for its specific actions, is the likely mechanism for exploitation, leading to the delivery of a secondary payload. The embedded URL is likely part of the exploit chain or payload delivery.

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.
