T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains numerous external links, with one prominent URL pointing to a suspicious domain ('ponafet.ru') that is likely used for phishing or malware distribution. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of outbound links, suggesting an attempt to generate traffic or distribute content. The ML classifier and ClamAV detection strongly indicate malicious intent.

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://ponafet.ru/strik?utm_term=the+story+of+us+boom+worksheet+answers
