The PDF file contains a large number of embedded links, many of which point to external PDF files hosted on various domains, including a known malicious redirector. The primary malicious link is https://ttraff.ru/pify?keyword=decarboxylation+of+carboxylic+acid+pdf, which is likely used to redirect users to further malicious content. The document body itself is heavily obfuscated and contains metadata indicating it was generated by wkhtmltopdf, suggesting it was not intended for legitimate user consumption but rather as a vehicle for link distribution.
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=decarboxylation+of+carboxylic+acid+pdf
