T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is identified as malicious by multiple heuristics, including a high-confidence ML classifier and ClamAV detection. The presence of an external URI pointing to 'trafffi.ru' suggests a phishing attempt, likely related to financial information. Although no scripts were explicitly extracted, the PDF structure and embedded URI indicate a malicious intent to redirect the user to a potentially harmful site.

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=wizz+air+holdings+london+stock+exchange PDF link annotation
