MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains a fake CAPTCHA lure, which is a common social engineering tactic to trick users into interacting with malicious content. It also embeds multiple URLs, likely intended to redirect users to sites offering exploits or further malware downloads. The presence of these elements strongly suggests a phishing or malware distribution attempt.
