T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, with one specifically pointing to 'traffset.ru' and a query parameter suggesting a lure for 'best keygen music'. ClamAV and ML classifiers strongly indicate maliciousness, identifying it as a phishing or trojan PDF. The presence of embedded links suggests an attempt to redirect the user to a malicious site for further exploitation or credential harvesting.

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://traffset.ru/123?utm_term=best+keygen+music
