T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains an embedded URL that mimics a search engine result for a common educational query. This technique is often used to direct users to malicious websites. The heuristic 'PDF_SEO_LINK_FARM' indicates the presence of numerous external links, suggesting a link farm designed to improve search engine ranking or distribute malicious content. ClamAV detection further confirms the malicious nature of the file.

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://baarspo.ru/wb?keyword=how%20to%20do%20trigonometric%20ratios%20on%20a%20calculator
