Malware Insights
The PDF file contains a large number of embedded links, many of which point to external resources, a technique often used for SEO poisoning or to redirect users to malicious sites. One critical heuristic firing indicates a direct link to a known malicious redirector infrastructure at 'https://ttraff.ru/pify?keyword=fusion+des+fichiers+pdf+en+ligne'. The document body, though partially corrupted, contains text related to PDF merging, likely a lure to entice users to click the malicious links. No scripts were extracted, but the presence of numerous links and the specific redirector URL strongly suggest a phishing or redirection attack.
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=fusion+des+fichiers+pdf+en+ligne
