T1566.001 Spearphishing Attachment

The file was detected as malicious by ClamAV and an ML classifier. It contains an embedded URI pointing to a suspicious domain, which is likely used to deliver a secondary payload or phish for credentials. Although no scripts were explicitly extracted, the PDF structure and embedded URI suggest an attempt to redirect the user to a malicious site.
