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

The PDF file contains a large number of external links, many of which point to potentially malicious or untrusted domains, indicating a link farm or SEO poisoning tactic. The primary heuristic identified an external URI pointing to 'evacdir.com', which is likely part of the malicious infrastructure. The document body is heavily obfuscated and does not provide clear textual lures, but the presence of numerous external links strongly suggests an attempt to redirect users to malicious content.
