T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, many of which point to external PDF files hosted on various domains, including Shopify. One critical heuristic identified a link to a known malicious redirector at 'https://ttraff.ru/pify?keyword=new+headway+plus+beginner+student+s+book+pdf'. This suggests the document is part of a link farm or SEO poisoning scheme designed to redirect users to malicious infrastructure. The document body contains garbled text but also includes the suspicious URL and metadata indicating it was generated by wkhtmltopdf.
Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
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.
-
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 https://ttraff.ru/pify?keyword=new+headway+plus+beginner+student+s+book+pdf
