T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a significant number of external links, identified as a 'PDF_SEO_LINK_FARM' heuristic, suggesting an attempt to direct users to potentially malicious websites. ClamAV detected the file as 'Pdf.Phishing.Trojan', and ML classification strongly indicated maliciousness. The embedded URLs, such as 'https://traffking.ru/strik?utm_term=yellow+apples+benefits' and multiple links hosted on 'cdn.sqhk.co', are likely part of this malicious infrastructure.

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://traffking.ru/strik?utm_term=yellow+apples+benefits PDF link annotation
