The PDF contains a critical heuristic firing for a malicious redirector link, which is also present in the document body. The document also exhibits characteristics of a link farm, with numerous embedded URLs, many pointing to Shopify domains. The primary malicious URL is a redirector that appears to be disguised as a link to 'past simple regular verbs exercises worksheets'. The presence of multiple Shopify links suggests an attempt to obscure the malicious destination or leverage seemingly benign domains for distribution.
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.cc/wb?keyword=past%20simple%20regular%20verbs%20exercises%20worksheets
