MITRE ATT&CK

T1204.002 Malicious File T1566.002 Spearphishing Attachment

The PDF file was detected by ClamAV as Pdf.Exploit.Dropped-78, indicating it contains an exploit. The presence of an embedded script payload and an embedded file further supports its malicious nature. While no specific document body content was extracted, the heuristics strongly suggest this PDF is designed to deliver a secondary payload.

Heuristics 5

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
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.
