The PDF file contains a significant number of embedded links, with one heuristic specifically identifying it as a PDF SEO link farm. The primary malicious URL identified is 'https://ttraff.ru/wix?keyword=hungary+focus+tree', which is flagged as a malicious redirector. The document body, though heavily obfuscated, contains this URL, suggesting it is the intended destination for users interacting with the document. The file's purpose appears to be to lure users to this 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/wix?keyword=hungary+focus+tree
