T1059.001 PowerShell
The PDF contains a link farm designed to manipulate search engine results, directing users to a malicious redirector. The document body, though heavily obfuscated, contains the URL 'https://ttraff.ru/wb?keyword=biology%20notes%20for%20class%2012%20chapter%20wise%20pdf%20hsc', which is flagged as malicious. The presence of numerous benign-looking Shopify links suggests an attempt to camouflage the malicious redirector within a larger set of URLs.
Heuristics 4
-
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.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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/wb?keyword=biology%20notes%20for%20class%2012%20chapter%20wise%20pdf%20hsc
