MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF contains a large number of embedded links, many pointing to benign Shopify domains, but one critical link directs to a known malicious redirector at 'ttraff.com'. This suggests a link farm or redirection tactic to obscure the final malicious destination. The ML classifier strongly flagged this PDF as malicious, supporting the redirector link finding. The document body text, though garbled, contains the title 'Edible leaves of the tropics pdf' and the URL 'https://ttraff.com/pify?keyword=edible+leaves+of+the+tropics+pdf', indicating the lure content and the initial malicious redirect. No scripts were extracted from this sample.

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.
URL https://ttraff.com/pify?keyword=edible+leaves+of+the+tropics+pdf
