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 these links, http://evacdir.com/..., appears to be a download URL for a malicious payload. The document body is heavily obfuscated and does not provide direct clues to the user's intent, but the heuristic firings strongly suggest a malicious download lure.
