Malware Insights
The PDF contains a high number of embedded links, many pointing to what appears to be a link farm designed for SEO manipulation. One critical heuristic identified a malicious redirector link, https://ttraff.ru/wix?keyword=frases+para+el+llenado+de+boletas, which is likely the primary malicious payload delivery mechanism. The document body, though partially corrupted, contains text related to filling out ballots and the authoring application, suggesting a lure to trick users into clicking the malicious link. No scripts were extracted, but the PDF structure and link farm indicate a malicious intent to redirect users to harmful content.
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/wix?keyword=frases+para+el+llenado+de+boletas
