This PDF document was flagged as malicious by ML classifiers and ClamAV, indicating a high likelihood of malicious intent. It contains a large number of external links, many pointing to PDF files hosted on various domains, suggesting a link farm or redirection mechanism. The primary external URL, https://mezovuduw.ru/aws?utm_term=holmes+humidifier+cleaning+vinegar, appears to be the initial lure, potentially leading to further malicious content or phishing attempts.

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://mezovuduw.ru/aws?utm_term=holmes+humidifier+cleaning+vinegar
