MITRE ATT&CK

T1204.002 Malicious File

The PDF file 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' strongly suggests it's a dropper for further malicious activity. The embedded file 'embedded_file_obj0008.bin' is likely the delivered payload. No document body text was available for analysis, but the presence of embedded scripts and the ClamAV signature point to an exploit-based attack pattern.

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.
