MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. The document body, though partially corrupted, contains the phrase 'Peso ideal para hombres por edad y estatura' which suggests a lure. The primary purpose appears to be directing users to a network of linked PDF documents hosted on various domains, likely for SEO spam or to distribute further malicious content.

    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
