T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF file was detected as malicious by ClamAV and an ML classifier, exhibiting characteristics of a phishing or malware distribution lure. It contains a large number of external links, many pointing to PDF files hosted on various domains, suggesting a link farm or SEO poisoning tactic. The embedded URLs, such as 'https://traffine.ru/aws?utm_term=funny+anchoring+script+for+dance+performance', are likely part of this malicious infrastructure. No scripts were extracted, but the PDF structure and heuristics indicate a deliberate attempt 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.

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://traffine.ru/aws?utm_term=funny+anchoring+script+for+dance+performance
