T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, with one heuristic specifically identifying a 'PDF link farm' designed to boost SEO. The primary malicious URL, 'https://jumiwimov.ru/wb?keyword=landforms%20worksheet%20for%20grade%202', suggests a lure to a website that may host malicious content or phishing pages. While no scripts were explicitly extracted, the presence of external links and the ML classifier's high confidence score indicate a malicious intent, likely related to driving traffic to potentially harmful sites.

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.

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://jumiwimov.ru/wb?keyword=landforms%20worksheet%20for%20grade%202 PDF link annotation
