MITRE ATT&CK

T1204.002 Malicious File T1553.005 Mark-of-the-Web Bypass

The PDF contains embedded content and a script payload, as indicated by the PDF_EMBEDDED and PDF_EMBEDDED_SCRIPT_PAYLOAD heuristics. ClamAV detection as Pdf.Exploit.Dropped-78 further confirms its malicious nature. The embedded file 'embedded_file_obj0008.bin' is likely the delivered payload. The XFA form structure suggests a potential exploit vector.

Heuristics 6

ClamAV: Pdf.Exploit.Dropped-78 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Dropped-78
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
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
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.
