T1059.007 JavaScript
This PDF file exhibits characteristics of a phishing or malware distribution lure. It contains a high number of embedded URLs pointing to various domains, suggesting an attempt to redirect users to malicious content. The 'ML_NYX_PDF_MALICIOUS' and 'CLAMAV_DETECTION' heuristics, along with the 'PDF_SEO_DISPOSABLE_LINK_FARM' finding, strongly indicate malicious intent. No scripts were extracted, but the document's structure and embedded links are designed to facilitate malicious redirection.

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.
-
Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARMSmall PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.

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://pistant.ru/uplcv?utm_term=how+to+grant+root+access+on+android PDF link annotation
