T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, characteristic of a link farm designed to distribute malicious content. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of outbound links, suggesting an attempt to redirect users to potentially harmful websites. The presence of a fake invoice lure further supports the phishing or scamming intent.

Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
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://trafffi.ru/strik?utm_term=guided+reading+lesson+plan+template+pdf
