T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged by ClamAV as Pdf.Phishing.Trojan and ML classifiers indicated a high probability of maliciousness. The presence of a large number of external links, including the primary URL 'https://krisoc.ru/pbw?utm_term=wolfteam+kurt+hilesi+nas%25C4%25B1l+indirilir', suggests a link farm or phishing attempt. While no scripts were directly extracted, the PDF structure and heuristic firings point towards a malicious document designed to redirect users to potentially harmful content.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.

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://krisoc.ru/pbw?utm_term=wolfteam+kurt+hilesi+nas%25C4%25B1l+indirilir
