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

The file is a PDF containing an embedded URI pointing to a suspicious domain, identified as malicious by ClamAV and ML classifiers. The document body is heavily obfuscated, but the presence of external links suggests an attempt to redirect the user to a malicious site. No scripts were extracted, but the PDF structure itself facilitated the embedding of a malicious URL.
