T1204.002 Malicious Link
The PDF contains a mass of external links, many pointing to Shopify domains, but one critical link redirects to a known malicious domain. The document body contains text related to 'baixar free pdf compressor' and the malicious URL, indicating a lure to download or interact with malicious content. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK strongly suggests the primary intent is to redirect users to harmful sites.
