T1204.002 Malicious Link
The PDF contains embedded links, one of which, 'https://ttraff.ru/pify?keyword=fannie+mae%252F+freddie+mac+guidelines', is flagged as a malicious redirector. The document body, though partially corrupted, contains text related to 'Fannie mae/ freddie mac guidelines' and the wkhtmltopdf application, suggesting a lure to disguise malicious content. The presence of a link farm further indicates an attempt to distribute malicious content or engage in SEO manipulation for malicious purposes.
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.
-
Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
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=fannie+mae%252F+freddie+mac+guidelines
