Why these techniques?

The stored XSS vulnerability in REDCap's messenger allows authenticated attackers to inject and persist malicious JavaScript, which executes in other users' browser contexts upon viewing messages. This facilitates exploiting public-facing web applications (T1190), stealing web session cookies (T1539), and extracting credentials from web browsers (T1555.003).
