T1566.001 Spearphishing Attachment
The PDF contains embedded JavaScript and numerous external URIs, indicating an attempt to redirect the user to potentially malicious websites. The heuristic 'PDF_SEO_DISPOSABLE_LINK_FARM' and the ClamAV detection 'Pdf.Phishing.Trojan-d2528dad23a95d95-d2528dad23a95d95-10044376-0' strongly suggest a phishing or malware distribution campaign. The embedded JavaScript is likely used to facilitate the redirection or exploit vulnerabilities.

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.
-
Embedded JS stream low PDF_JSPDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
-
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://pixomot.ru/uplcv?utm_term=tubidy+free+music+download+for+android+tablet PDF link annotation
