T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains a heuristic indicating it is a link farm, with one specific URL identified as a potential lure for financial calculations. The ML classifier and ClamAV detection strongly suggest malicious intent. While no scripts were extracted, the presence of embedded external links and the 'Fake invoice / payment lure' heuristic point towards a phishing or redirection attack.

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://traffnew.ru/123?utm_term=chit+fund+calculator+for+2+lakhs
