T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a large number of external links, many pointing to PDF files hosted on services like Weebly and sqhk.co, indicating a link farm. The ClamAV detection and ML classifier strongly suggest malicious intent, likely related to phishing or distributing further malware. The embedded URL and the PDF_SEO_LINK_FARM heuristic confirm the primary function is to redirect users to a network of potentially malicious or SEO-manipulated content.

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://resalured.ru/wix?keyword=frog+dissection+procedure+ppt
