T1059.001 PowerShell
The PDF contains embedded JavaScript and a critical heuristic firing for a malicious redirector link. The primary link, https://ttraff.com/pify?keyword=concepto+de+certificacion+de+calidad+pdf, is designed to redirect users to potentially harmful content. The document also contains a large number of external PDF links, many hosted on Shopify, which is indicative of a link farm used for SEO manipulation or to obscure malicious destinations. The embedded JavaScript likely facilitates the redirection or exploits vulnerabilities.
Heuristics 4
-
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 JS stream low PDF_JSPDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
-
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.com/pify?keyword=concepto+de+certificacion+de+calidad+pdf
