MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The document displays a fake CAPTCHA, a common lure to trick users into clicking malicious links or downloading further payloads. The presence of multiple URLs, including one pointing to 'how-to-hack' content, suggests a phishing or social engineering attempt. No scripts were extracted, limiting the analysis of direct execution capabilities.
