Malware Insights
The PDF contains a critical heuristic indicating it links to known malicious redirector infrastructure via the URL https://ttraff.com/wix?keyword=difference+between+wafer+lug-style+butterfly+valve. Additionally, it exhibits characteristics of a PDF link farm, embedding numerous external links, with the primary one pointing to static.usrfiles.com. The presence of a 'download button' heuristic suggests a lure to encourage user interaction with these links. No scripts were extracted, and the document body is heavily obfuscated, preventing a deeper analysis of its specific intent beyond the redirection.
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.com/wix?keyword=difference+between+wafer+lug-style+butterfly+valve
