MITRE ATT&CK

T1204.002 Malicious File T1566.002 Spearphishing Attachment

The file is identified as malicious by ClamAV with the signature Pdf.Exploit.Agent-36962, and a machine learning classifier also flagged it with high confidence. The presence of PDF-specific heuristics like 'PDF_EMBEDDED', 'PDF_XFA', and 'PDF_ACROFORM_BUTTON' further indicates an exploit attempt. The embedded URL, while seemingly benign, is associated with the document's structure, suggesting it might be part of the exploit chain.

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.
