T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous embedded links, with a critical heuristic identifying it as a PDF SEO link farm. One prominent URL, 'https://traffine.ru/strik?keyword=eureka+math+grade+3+answer+key', is presented as a lure for an answer key. ClamAV detection and ML classification strongly indicate malicious intent, likely for phishing or SEO spam.

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://traffine.ru/strik?keyword=eureka+math+grade+3+answer+key
