T1059.007 JavaScript
T1203 Exploitation for Client Execution
The PDF file contains a malformed stream and an embedded URL that is likely malicious, as indicated by ML classification and ClamAV detection. The document body, though heavily corrupted, suggests a lure related to a Nintendo Switch 2, aiming to trick users into clicking the embedded link. This link likely leads to a phishing page or a second-stage malware download.

Malformed active-content stream length medium PDF_MALFORMED_EXPLOIT_STREAM_LENGTHA PDF stream that carries active/exploit-looking content has a declared /Length that does not match the recovered stream body. Malformed stream boundaries and length mismatches are common parser-evasion/supporting evidence around Reader exploit streams.

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://seumenha.ru/strik?utm_term=is+there+a+nintendo+switch+2+coming+out PDF link annotation
