Malware Insights
The PDF contains a large number of embedded links, many of which point to external PDF files, suggesting a link farm for SEO manipulation. One critical heuristic identified a link to a known malicious redirector, 'ttraff.ru', which is used to obscure the final destination. The document body, though heavily obfuscated, contains the string 'Halloween word search puzzle pdf' and a URL that matches the redirector, indicating a social engineering lure. The presence of numerous benign-looking Shopify links alongside the malicious redirector suggests an attempt to blend in. No scripts were extracted from this sample.
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=halloween+word+search+puzzle+pdf
