T1204.001 Malicious Link
T1059.001 PowerShell
The PDF contains a heuristic firing for a malicious redirector link, pointing to `https://ttraff.cc/wix?keyword=cards+against+humanity+4th+expansion`. The document body, though heavily obfuscated, also contains this URL. This indicates the primary intent is to redirect the user to a potentially harmful site, likely for phishing or malware distribution. The presence of numerous other PDF links, many pointing to benign content, suggests a link farm or SEO poisoning tactic to mask the malicious URL.
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.
-
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=cards+against+humanity+4th+expansion
