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

The PDF file contains a large number of external links, identified as a link farm, which is a common technique for distributing malware or redirecting users to malicious websites. The primary URL, http://evacdir.com/..., appears to be a staging point for further malicious activity. The heuristic firings indicate a deliberate attempt to create a deceptive document structure for malicious purposes.
