T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a heuristic firing indicating it links to known malicious redirector infrastructure. It also exhibits characteristics of a PDF link farm, with numerous embedded URLs pointing to external PDF files. The primary malicious URL identified is https://ttraff.ru/pify?keyword=algebra+and+trigonometry+for+college+students+2nd+edition+pdf+free, which is likely used to redirect users to further malicious content. The document body contains garbled text but also includes the same malicious URL and several other PDF links.
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=algebra+and+trigonometry+for+college+students+2nd+edition+pdf+free
