MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links, as indicated by the PDF_SEO_LINK_FARM heuristic. The document body, though partially corrupted, contains a URL pointing to 'thehnossaproject.com' and mentions 'imagenes de animales acuaticos terrestres y aereos para colorear', suggesting a lure for users interested in coloring pages. The primary function appears to be directing users to a network of linked PDF files hosted on various domains, likely for SEO spam or to distribute further malicious content.
