T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, many of which point to Shopify domains hosting other PDFs, a technique often used for SEO poisoning. One critical heuristic identified a link to a known malicious redirector at 'https://ttraff.ru/pify?keyword=interpreting+graphs+of+functions+answer+key'. The document body also contains this URL and other PDF links, suggesting the primary goal is to redirect the user to malicious infrastructure.
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.
