Malware Insights
The PDF file contains a malicious redirector link and a large number of external PDF links, masquerading as a lure to download embedded video. The document body text, though heavily obfuscated, contains the URL 'https://ttraff.cc/wix?keyword=download+embedded+video', which is flagged as a malicious redirector. The heuristic 'SE_BROWSER_INSTALL_LURE' indicates the document's content is designed to trick users into installing software or extensions, a common social-engineering path for malware delivery. The presence of numerous benign-looking PDF links, while potentially a link farm, also serves to distract from the primary malicious URL.
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.cc/wix?keyword=download+embedded+video
