T1059.007 JavaScript
T1203 Exploitation for Client Execution
This PDF document contains numerous external links, suggesting a link farm or redirection scheme. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' indicates that the document may be part of a multi-stage attack, potentially requiring a password to decrypt a payload. The ML classifier and ClamAV detection strongly indicate malicious intent, likely involving the exploitation of PDF vulnerabilities to execute further malicious code.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host.

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://bologen.ru/wix?keyword=lg+g5+hidden+menu+unlock
