T1566.002 Spearphishing Attachment
T1204.001 User Execution: Malicious Link
The PDF contains a large number of embedded links, many of which point to a link farm hosted on cdn.shopify.com. One of these links, https://ttraff.com/wix?keyword=nof+osteoporosis+guidelines+2014, is identified as a malicious redirector. The document body, though heavily obfuscated, contains this same URL, suggesting the primary intent is to trick the user into visiting a malicious site.
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.
