MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF file contains an embedded URI pointing to a suspicious domain, which is a strong indicator of a phishing or malware distribution attempt. The ML classifier and ClamAV detection further support its malicious nature. Although no scripts were explicitly extracted, the presence of external URIs suggests the document is designed to redirect the user to a malicious site, likely for further exploitation or credential harvesting.
