T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV and an ML classifier. It contains an embedded URI that points to a URL, which is a common tactic for phishing or malware distribution. Although the URL itself was flagged as benign, the overall detection suggests malicious intent. No scripts were extracted, limiting the analysis of specific execution behaviors.
