MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File T1059.001 PowerShell

The ML classifier and ClamAV detection strongly indicate this PDF is malicious, likely exploiting a vulnerability. The presence of embedded files and an XFA form suggests an attempt to execute arbitrary code. The embedded URL, while not directly malicious in reputation, is part of the document's structure that facilitates the exploit.

Heuristics 5

ClamAV: Pdf.Exploit.Agent-36962 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-36962
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
AcroForm button with action trigger low PDF_ACROFORM_BUTTON

PDF contains a /Btn form field together with a SubmitForm/URI/Launch/JS trigger — this is the building block of fake 'Download' or 'Open' button overlays used in PDF phishing lures
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.
