T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The PDF document was identified as malicious by an ML classifier and contains a large number of external links, characteristic of a link farm. The primary purpose appears to be directing users to a multitude of other PDF files hosted across various domains. The document body itself contains garbled text and a few URLs, reinforcing the link farm nature of the sample.

Heuristics 4
-
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.
-
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://automatischtranscriberen.nl/uploads/1/3/1/4/131437484/131437484.html#introducci%C3%B3n+a+la+l%C3%B3gica+matem%C3%A1tica PDF link annotation
