T1204.002 Malicious Link
The PDF file contains a heuristic firing for a malicious redirector link, specifically pointing to 'https://ttraff.ru/wix?keyword=frozen+2019+sub+indo'. This URL is presented within the document body, likely as a lure. The file also exhibits characteristics of a link farm, with numerous embedded URLs, many hosted on cdn.shopify.com. The ML classifier strongly flagged this PDF as malicious. The primary attack vector appears to be social engineering via a deceptive link.

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.
-
