T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains an embedded URL and lures suggesting credential harvesting or a payload download. The 'SE_MFA_LURE' and 'SE_PASSWORD_ARCHIVE_LURE' heuristics indicate the document is designed to trick users into providing sensitive information or bypassing security measures. The ML classifier strongly flagged this PDF as malicious, and the embedded URL is a primary indicator of a phishing or download attempt.

- Nyx PDF Classifier malicious score 1.0000
Heuristics 5
-
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
-
MFA / one-time-code harvesting lure high SE_MFA_LUREDocument asks for a one-time code, authenticator approval, or MFA confirmation — consistent with credential phishing kits that steal session tokens or abuse multi-factor authentication
-
External URI info PDF_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe 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_URLOne 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.URL https://traffnew.ru/123?keyword=open+itunes+account+login PDF link annotation
