MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.001 Malicious Link T1059.001 PowerShell

The PDF file contains a large number of embedded links, many of which point to Shopify domains, but one specific URL, 'https://ttraff.cc/wix?keyword=mario+kart+64+online+emulator', is flagged as a malicious redirector. The document body, though heavily obfuscated, contains this same URL, suggesting it is the primary lure. The presence of numerous links, including the malicious one, indicates a link farm or redirection tactic to obscure the final malicious destination. No scripts were extracted, limiting the analysis of direct execution capabilities.

Heuristics 3

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF 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_FARM

Small 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.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
