T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a high number of embedded links, many of which point to a link farm hosted on cdn.shopify.com, and one critical link redirects to a known malicious domain (ttraff.com). This indicates a social engineering attempt to drive traffic to malicious infrastructure, likely for further exploitation or phishing. The ML classifier also strongly flagged this PDF as malicious.

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.
