T1059.007 JavaScript
The PDF contains numerous external links, many pointing to Weebly and Strikingly domains, suggesting a link farm or SEO manipulation tactic. One primary URL, 'https://queure.ru/pbw?utm_term=descargar+hirens+boot+15.2+iso+espa%25C3%25B1ol+mega+gratis', appears to be a lure for downloading software. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' indicates the document likely instructs the user to decrypt an archive, a common method to evade initial security checks. ClamAV detection further confirms its malicious nature.

Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning

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://queure.ru/pbw?utm_term=descargar+hirens+boot+15.2+iso+espa%25C3%25B1ol+mega+gratis
