T1566.001 Spearphishing Attachment
The PDF contains numerous embedded URLs, many of which point to disposable domains and are structured as link farms, indicating a phishing or redirection attempt. ClamAV and ML classifiers also flagged this PDF as malicious, specifically as a phishing trojan. While no scripts were explicitly extracted, the PDF structure and URL patterns strongly suggest an intent to redirect users to malicious sites, aligning with spearphishing tactics.

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 http://kimkhimientrung.com/uploads/image/files/rijuwubafokijefamo.pdf In PDF document text
