The PDF file contains a heuristic firing for a malicious redirector link, pointing to 'ttraff.me'. The document body, though heavily obfuscated, contains a string that appears to be a URL related to 'multi-step equations coloring worksheet pdf', which aligns with the malicious redirector's query parameter. The file also exhibits characteristics of a link farm, with numerous embedded URLs, many pointing to Shopify, likely to obscure the malicious destination. The primary malicious IOC is the redirector URL.
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.me/wix?keyword=multi-step+equations+coloring+worksheet+pdf
