T1566.001 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a large number of embedded links to external PDF files hosted on various domains, indicating a link farm or redirection strategy. ClamAV identified this as 'Pdf.Phishing.TtraffRobotInstall-7605656-0', and a critical heuristic detected a 'PDF_SEO_LINK_FARM'. The document body text is heavily obfuscated and does not provide clear intent, but the overall structure strongly suggests a phishing or malware distribution campaign. No scripts were extracted from this sample.

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://andrelamy.eu/uploads/1/3/0/5/130588658/nuvawapuratate.pdf In PDF document text
