MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.007 JavaScript

The file is a PDF that contains an embedded URL pointing to a suspicious domain, likely intended for phishing or malware distribution. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' suggests the document may be part of a multi-stage attack, potentially involving a password-protected archive. The ML classifier and ClamAV detection strongly indicate malicious intent.

ClamAV: Pdf.Phishing.Trojan-d2568dad23a94d95-d2568dad23a94d95-10044375-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Phishing.Trojan-d2568dad23a94d95-d2568dad23a94d95-10044375-0
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE

Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
External URI info PDF_URI

PDF contains an external URL action
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL

The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
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.
