T1204.002 Malicious Link
The PDF file was flagged by a critical heuristic for linking to a known malicious redirector, ttraff.link. Additionally, it contains a large number of external PDF links, suggesting a link farm designed to direct users to potentially harmful content. The ML classifier also strongly indicated maliciousness. The primary malicious IOC is the redirector 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.
