T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains a heuristic firing for a link farm, embedding numerous external links to other PDF files. One of these links, http://antiviruseprotectserviceonline.site/uploads/1/3/0/6/130620687/130620687.html#how+to+charge+the+shark+navigator+freestyle, is directly present in the document body. This suggests a social engineering attempt to direct the user to malicious content hosted on external sites.

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.
-
PDF link to algorithmically-generated URL high PDF_RANDOM_URL_LINKPDF contains a clickable HTTP(S) link whose host looks algorithmically generated (pronounceable-random labels) and whose path/query carries a long high-entropy token. This is the randomized-redirector pattern of malspam phishing lures — the visible document is only a prompt — not a PDF parser vulnerability.
-
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://antiviruseprotectserviceonline.site/uploads/1/3/0/6/130620687/130620687.html#how+to+charge+the+shark+navigator+freestyle PDF link annotation
