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

The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. One of the primary links, http://dormister.com/argonaunts.ZG93bmxvYWR8aXA0TlRGblkzeDhNVFkxTnpBek5qSXlNM3g4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA.eagles/lipped/moded/dalton/RmlmYSAyMgRml, appears to be a lure for downloading a payload. The document body is heavily obfuscated and does not provide clear textual content for analysis.
