T1059.001 PowerShell
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to ttraff.ru. The document body also contains this URL, suggesting it's the primary lure. Additionally, a PDF link farm heuristic indicates the document is designed to host numerous external links, likely for SEO manipulation or distributing malicious content. The presence of multiple Shopify URLs, some confirmed benign and others unknown, suggests an attempt to blend in with legitimate content while hosting the malicious redirector.
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=cambridge+academic+english+upper+intermediate+pdf+download
