T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://cctraff.ru/123?utm_term=circuit+worksheet+ks3'. This, combined with a high ML classifier score and ClamAV detection, strongly indicates a phishing or malware distribution attempt. Although no scripts were extracted, the presence of a malicious URL within the document body is sufficient evidence for this attack pattern.

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://cctraff.ru/123?utm_term=circuit+worksheet+ks3
