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

The PDF document contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. One of these links, http://evacdir.com/, appears to be a download lure. The document body is heavily obfuscated and does not provide clear textual clues, but the presence of numerous external links strongly suggests a phishing or malware distribution attempt.
