T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious Link

The document displays a fake CAPTCHA lure to deceive users into clicking a link, which is a common tactic for delivering malware. The embedded URL points to a resource that likely serves as a download for a second-stage payload. No scripts were extracted from this sample, limiting further analysis of its execution flow.
