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

The PDF document contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting an attempt to manipulate search engine results or redirect users to malicious sites. One prominent URL, http://evacdir.com/Vm94eWdlbiBDNGQgUGx1Z2luIDQyVm9/crypto.kalosmi/porcaro=segmented/skyscraper=/breadmakers=ZG93bmxvYWR8a1E3YlhrME1YeDhNVFkxTkRnNU16RTVNWHg4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA, is directly embedded and likely serves as a primary download or redirection point. The document body was unreadable, but the link farm strongly indicates a malicious intent to drive traffic to potentially compromised or malicious content.

  • Embedded URL info EMBEDDED_URL
