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 text related to 'Yoremia calificaciones primaria 2019' and references the wkhtmltopdf tool, suggesting a lure document. The primary function appears to be acting as a link farm, directing users to numerous external PDF files hosted on various domains. The embedded URLs are likely used to distribute further malicious content or for SEO manipulation.
