T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged by ClamAV as a phishing trojan and a machine learning model assigned a high probability of maliciousness. The heuristic 'PDF_SEO_LINK_FARM' indicates the presence of numerous external links, with one prominent example being 'https://cdn.sqhk.co/zunesunatiri/hjhhjiN/rijafamibokuloxabifamer.pdf'. The embedded URL 'https://lozipotod.ru/wix?keyword=one+more+cup+of+coffee+lyrics+damian+marley' further suggests a lure or phishing attempt. While no scripts were explicitly extracted, the nature of the PDF and its embedded links strongly suggest it's used as a delivery mechanism for malicious content, likely via spearphishing.

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://lozipotod.ru/wix?keyword=one+more+cup+of+coffee+lyrics+damian+marley
