T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a large number of external links, a technique often used for SEO poisoning or to redirect users to malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the ML classifier output strongly indicate malicious intent. The embedded URLs are likely part of this redirection scheme.

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.

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://rickydemedeiros.com/uploads/1/3/0/3/130379132/moxurokenom-zilibidovejez.pdf In PDF document text
