T1059.007 JavaScript
The PDF document contains a large number of external links, many of which are obfuscated or point to link farms, suggesting a phishing or SEO spam campaign. The embedded URL 'https://jacksth.ru/strik?utm_term=how+to+map+midi+controller+in+fl+studio+20' is presented as a lure to disguise the malicious intent. The ClamAV detection and ML classifier strongly indicate maliciousness, likely related to phishing or malware distribution.

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://jacksth.ru/strik?utm_term=how+to+map+midi+controller+in+fl+studio+20
