T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains an embedded URL that directs users to a site offering app downloads, suggesting a lure for potentially malicious software. The ML classifier strongly flagged this PDF as malicious. While no scripts were directly extracted, the presence of an external URI and the overall suspicious nature indicated by the ML model point towards a phishing or malware distribution attempt.

Heuristics 3
-
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://trafffe.ru/123?keyword=app+market+apk+download+ios PDF link annotation
