Malware Insights
The PDF file contains numerous embedded links, with a critical heuristic firing indicating it's a malicious redirector. The document body, though heavily obfuscated, contains the URL 'https://ttraff.ru/pify?keyword=possessive+adjectives+exercises+1o+eso+pdf', which is flagged as malicious. Additionally, a large number of links to external PDFs were found, suggesting a link farm or SEO manipulation tactic, with one such link pointing to 'https://cdn.shopify.com/s/files/1/0429/1955/9335/files/bacillus_anthracis_en_bovinos.pdf'. The primary attack pattern appears to be leveraging these links for redirection or hosting further malicious content.
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=possessive+adjectives+exercises+1o+eso+pdf
