T1204.001 User Execution: Malicious Link
T1059.001 PowerShell
The PDF file contains a critical heuristic indicating it's a malicious redirector link, pointing to 'ttraff.ru'. This URL is presented within the document body, disguised as a download link. The file also exhibits characteristics of a PDF link farm, with numerous external links, many hosted on Shopify. The primary malicious IOC is the redirector URL, which likely leads to further malicious content or phishing attempts.
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.
-

-
