T1204.002 Malicious Link
This PDF file was detected as malicious by ClamAV (Pdf.Dropper.Agent-8946154-0) and flagged by an ML classifier. It contains a large number of external links, many of which point to other PDF files hosted on similar domains, indicating a link farm or SEO abuse pattern. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' suggests the document may be intended to trick users into downloading an archive with provided password, a common tactic for evading gateway security.

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. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
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 http://utfarmmeats.com/uploads/1/3/1/3/131378990/131378990.html#blynk+app+tutorial+pdf PDF link annotation
