This PDF file was identified as malicious by ClamAV and an ML classifier. It contains a significant number of external links, a technique often used for SEO manipulation or to redirect users to malicious sites. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' suggests it may also be used to trick users into providing passwords for archives, potentially to bypass gateway scanning. No scripts were extracted, but the presence of external links indicates a likely intent to redirect the user to a compromised or malicious resource.

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://trafffi.ru/123?utm_term=bluetooth+rc+car+controller+app
