T1204.001 Malicious Link
The PDF file contains a heuristic firing for a malicious redirector link, specifically pointing to 'https://ttraff.cc/wix?keyword=auto+hemoterapia+que+%25C3%25A9+autismo'. This URL is presented within the document's content, suggesting a social engineering attempt to trick the user into visiting a potentially harmful site. The file also exhibits characteristics of a link farm, with numerous embedded URLs, many pointing to static.usrfiles.com. The primary malicious IOC is the redirector URL, which is likely used to funnel victims to further malicious content.
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.
-
