T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was detected as malicious by ML classifiers and ClamAV, indicating a high likelihood of malicious intent. The embedded URL, https://kuzutuzo.ru/strik?utm_term=uyirai+tholaithen+athe+unnil+thaano+album+song+download, is the primary indicator of a phishing or malware distribution attempt. Although no scripts were explicitly extracted, the PDF structure and the presence of external URIs suggest it's designed to exploit users through social engineering, likely leading to a download or further compromise.

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://kuzutuzo.ru/strik?utm_term=uyirai+tholaithen+athe+unnil+thaano+album+song+download
