T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, with one prominent URL leading to 'crewmak.ru' and a query string suggesting a lure for 'Whatsapp plus apk download'. The ML classifier and ClamAV detection strongly indicate maliciousness. The PDF's structure and embedded links suggest it's part of a link farm or phishing campaign designed to redirect users to potentially malicious sites.

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://crewmak.ru/pbw?utm_term=whatsapp+plus+apk+download+latest+version+v6+40+free+2019
