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

The PDF contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or redirection scheme. One prominent URL, http://evacdir.com/firework.equifax?guiness=R2VvbWV0cmlhRGVzY3JpcHRpdmFOYWthbXVyYVBkZgR2V/prancer&dyskinesia=ZG93bmxvYWR8RXY3TmpBMU1IeDhNVFkxTkRjNE1EZzNPWHg4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA, is directly embedded and likely serves as a distribution point for malicious content. The document body is heavily obfuscated and does not provide clear textual lures.
