Malware Insights
The PDF contains a heuristic firing for a malicious redirector link, specifically pointing to 'https://ttraff.ru/pify?keyword=strength+of+materials+multiple+choice+questions+pdf'. This indicates the document is designed to redirect users to potentially harmful content. Additionally, the PDF exhibits characteristics of a link farm, embedding numerous external links, many of which point to Shopify domains, likely as a tactic to improve search engine ranking for malicious content. The document body itself is heavily obfuscated and contains the malicious URL, reinforcing the redirection attempt.
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=strength+of+materials+multiple+choice+questions+pdf
