T1204.002 Malicious Link
The PDF document contains numerous links, masquerading as a solutions manual to entice users to click. The primary link, 'https://ttraff.ru/pify?keyword=organic+chemistry+klein+2nd+edition+solutions+manual', is identified as a malicious redirector. The document also exhibits characteristics of a link farm, with many embedded URLs pointing to PDF files hosted on various domains, including multiple Shopify subdomains. No scripts were extracted from this sample.
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.
