T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains numerous links, many pointing to a link farm hosted on cdn.shopify.com, designed to obscure the ultimate destination. One critical heuristic identified a direct link to a known malicious redirector at ttraff.cc, which is likely the primary malicious payload delivery mechanism. The document body text, though partially corrupted, includes the same topic as the malicious URL, suggesting a lure to entice users to click the malicious link.
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.
