T1059.007 JavaScript
The PDF contains an embedded URI pointing to 'traffset.ru', which is flagged as suspicious. ML classifiers and ClamAV also indicate maliciousness, classifying it as a phishing trojan. The document body is heavily obfuscated, but the presence of the external URI is the primary indicator of malicious intent, likely leading to a phishing page or malware download.

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/aws?utm_term=avg+business++center PDF link annotation
