T1566.001 Spearphishing Attachment
This PDF file was flagged as malicious by multiple detection engines, including a high-confidence ML classifier and ClamAV, which identified it as Pdf.Exploit.Dropped-78. The presence of embedded scripts and an embedded file suggests it is designed to exploit vulnerabilities and download a secondary payload. The benign URLs extracted are likely unrelated to the malicious functionality.

Embedded file low PDF_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
Embedded script payload in PDF stream low PDF_EMBEDDED_SCRIPT_PAYLOADPDF 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.
