T1059.007 JavaScript
This PDF file was detected as malicious by ClamAV and a machine learning classifier, exhibiting characteristics of a phishing or malware distribution lure. It contains a mass of external links, many pointing to Weebly-hosted PDFs, suggesting a link farm designed to obscure the ultimate malicious destination. The primary malicious URL identified is `https://dugedepap.ru/strik?utm_term=cuales+son+los+personajes+principales+de+los+crimenes+de+la+calle+morgue`, which is likely used to redirect users to a malicious site.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
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://dugedepap.ru/strik?utm_term=cuales+son+los+personajes+principales+de+los+crimenes+de+la+calle+morgue PDF link annotation
