T1204.001 User Execution: Malicious Link

The PDF contains a heuristic firing for a malicious redirector link, which is also present in the document body. The document also contains a heuristic for a browser extension installation lure, indicating a social engineering attempt. The primary malicious URL identified is https://ttraff.club/wix?keyword=android+games+emulator+for+pc, which is likely used to redirect the user to a malicious site. The PDF also contains a link farm pointing to multiple PDFs hosted on static.usrfiles.com, though these specific links were classified as benign.
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.
-
Browser extension / update installation lure high SE_BROWSER_INSTALL_LUREDocument tells the user to install a browser extension, plugin, viewer, or browser update to view content — a common social-engineering path for credential theft and malware installation
-
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=android+games+emulator+for+pc
