Malware Insights
The PDF file was flagged by multiple critical heuristics for containing malicious redirector links and a large number of external PDF links, suggesting a link farm or SEO abuse tactic. One of the embedded URLs, 'https://ttraff.ru/pify?keyword=calendar+2020+pdf', is identified as a known malicious redirector. The document body is heavily obfuscated and contains metadata indicating it was generated by wkhtmltopdf, but no executable scripts were extracted. The primary attack pattern appears to be leveraging a large number of links to potentially lure users to malicious sites or for SEO manipulation.

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.
