T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic, which is indicative of a phishing or redirection campaign. The ClamAV detection of Pdf.Phishing.TtraffRobotInstall-7605656-0 further supports this assessment. The document body contains garbled text but also lists several of the embedded URLs, reinforcing the attack pattern.

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://pianoninja.net/uploads/1/3/0/2/130289745/1230651.pdf In PDF document text
