The PDF file contains a critical heuristic firing for a malicious redirector link, pointing to 'ttraff.club'. The document body, though heavily obfuscated, contains the same URL and references a download for 'School 2017 ep 2 eng sub', indicating a lure. Additionally, a PDF link farm heuristic was triggered, with multiple links to Shopify-hosted PDFs, suggesting a broader campaign to distribute malicious content. 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.club/wix?keyword=school+2017+ep+2+eng+sub+download
