MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various domains. The document body contains Spanish text related to a restaurant project, which may serve as a lure. The primary function appears to be directing users to a network of linked PDFs, potentially for SEO spam or to host further malicious content.
