T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was identified as malicious by ML classifiers and ClamAV, indicating a high likelihood of malicious intent. It contains a large number of external links, with the primary URL being `https://seumenha.ru/wix?keyword=machinemuse%2527s+modular+powersuits+guide`. This suggests the document is part of a link farm or phishing campaign designed to redirect users to potentially harmful sites. The presence of numerous external links, many pointing to benign-looking PDFs, is characteristic of SEO poisoning or link farm tactics to improve search engine rankings for malicious content.

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://seumenha.ru/wix?keyword=machinemuse%2527s+modular+powersuits+guide
