T1566.001 Spearphishing Attachment
The file is a PDF that masquerades as an educational resource ('Math worksheet for 2nd grade') to trick users. It contains multiple embedded URLs, one of which is directly associated with the lure. The ML classifier and ClamAV detection strongly indicate malicious intent, likely related to phishing or malware distribution.

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/123?utm_term=math+worksheet+for+2nd+grade
