T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains numerous embedded links, identified as a link farm, likely intended to redirect users to malicious content or downloads. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' suggests the document may also instruct users to open a password-protected archive, a common tactic to bypass security scans. While no scripts were directly extracted, the presence of embedded URLs and the ML classification strongly indicate malicious intent.

Heuristics 5
-
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://host49.carmichaelnl.com/uploads/1/3/1/6/131636683/131636683.html#download+video+tutorials+free
