T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains an embedded URL that masquerades as a syllabus, a common lure for phishing attacks. The ML classifier strongly indicates maliciousness, and the presence of multiple external URLs suggests a distribution or redirection mechanism. No scripts were extracted, but the overall structure and heuristics point towards a spearphishing attachment used to deliver a payload or redirect to a malicious site.

Heuristics 3
-
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://trafficel.ru/aws?utm_term=bcom+sol+syllabus+pdf PDF link annotation
