T1204.002 Malicious Link
The PDF contains a link farm designed to redirect users to malicious sites, specifically leveraging a 'google chrome app windows 7' lure. The document body, though heavily obfuscated, contains references to this lure and numerous PDF links, indicating a social engineering attempt to trick users into downloading potentially malicious content or extensions. The primary malicious URL identified is ttraff.com, which is flagged as a redirector.
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
