MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document is identified as malicious by an ML classifier and contains a significant number of external links, characteristic of a link farm or SEO spam. The document body, though partially corrupted, contains text suggesting it is a PDF about human anatomy and physiology, likely a lure to encourage users to click on the embedded malicious links. The primary attack pattern involves tricking users into visiting a network of linked sites, potentially for further exploitation or to generate ad revenue.

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://stumblingmonkeydecals.com/uploads/1/3/1/3/131380786/131380786.html#livro+anatomia+e+fisiologia+humana+pdf
