MITRE ATT&CK

T1204.002 Malicious File T1566.002 Spearphishing Attachment

The file is a PDF document identified by ClamAV as Pdf.Exploit.Dropped-78, indicating it contains an exploit and likely drops a secondary payload. The presence of an embedded script payload and an embedded file further supports this. The document body contains obfuscated JavaScript-like code, suggesting an attempt to execute malicious actions upon opening.

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.
