T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
This PDF document is classified as malicious due to its structure, which includes a large number of external links to other PDF files, characteristic of a link farm or SEO poisoning attack. The document body contains text related to a 'Canon digital ixus 850 is manual', likely a lure to entice users to click on the embedded malicious URLs. No scripts were extracted, but the PDF_SEO_LINK_FARM heuristic indicates the primary malicious function is to redirect users to potentially harmful content.

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://hostmaster.artincanterbury.co.uk/uploads/1/3/0/2/130289278/130289278.html#canon+digital+ixus+850+is+manual PDF link annotation
