Malware Insights
The PDF file was identified as malicious due to the presence of numerous embedded links, a common tactic for distributing malware or leading users to phishing sites. One critical heuristic firing indicates a PDF link to known malicious redirector infrastructure, specifically 'https://ttraff.ru/wix?keyword=la+peste+camus+pdf'. Another heuristic identified a large number of external PDF links, with 'https://cdn.shopify.com/s/files/1/0434/8510/2237/files/pumolirelufisaregalu.pdf' being the first listed. The document body contains garbled text but includes the same malicious URL, reinforcing the attack vector.
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=la+peste+camus+pdf
