The PDF contains a link farm designed to redirect users to malicious infrastructure, specifically identified by the critical PDF_MALICIOUS_REDIRECTOR_LINK heuristic. The embedded URL 'https://ttraff.ru/pify?keyword=arrondir+un+nombre+d%25C3%25A9cimal+exercices+cm2+pdf' is a key indicator of this redirection. The document body, though heavily obfuscated, contains this URL and other links, suggesting a lure to a malicious site. The ML_NYX_PDF_MALICIOUS heuristic further supports the malicious classification.

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.
-
