T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a large number of external links, many pointing to Shopify domains hosting other PDFs, a technique often used for SEO poisoning or to obscure malicious redirects. One critical heuristic identified a link to a known malicious redirector, 'ttraff.cc', which is likely the primary malicious payload delivery mechanism. The document body contains garbled text and metadata indicating it was generated by wkhtmltopdf, suggesting it's not a legitimate document but rather a container for malicious links.
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.
