The PDF contains a heuristic firing for a malicious redirector link, directing users to a URL associated with malicious activity. Additionally, it exhibits characteristics of a link farm, embedding numerous external links, many of which point to Shopify domains. The document body, though heavily obfuscated, suggests a lure related to IELTS practice tests, likely intended to entice users to click the malicious link.
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=ielts%20general%20training%20reading%20practice%20test%20with%20answers%20pdf
