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

The PDF file contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various domains, suggesting a link farm or SEO manipulation tactic. One of the embedded URIs, http://74-123-76-231.mgwnet.com/uploads/1/3/0/5/130588956/130588956.html#sushi%3A+jiro+gastronomy, is directly referenced in the document body. The primary purpose appears to be directing users to these external resources, which could host malicious content or be part of a phishing campaign.

  • Embedded URL info EMBEDDED_URL
