Analysis of Cross-Site Request Forgery (CSRF) attack principles: beyond imagination

Cross-Site Request Forgery (XSS) is perhaps the most incomprehensible attack method, but the danger is also underestimated. In the "Open Web Application Security Project" (OWASP) List, CSRF (XSRF) is in the top 10. In short, malware forces the browser to execute commands that are not needed in the authenticated context.

Browser manufacturers are well aware of this hazard and have introduced some types of CSRF protection technology.

Despite this, attackers are constantly adapting their methods, and even combining multiple types of Web attacks to enlarge the harm (such as XSS and SQL injection ).

For example, a CSRF captures users' cookies through XSS (Cross-Site Scripting) and transfers funds out of users' bank accounts.

To defend against CSRF attacks, developers can deploy CAPTCHA on the form, use multi-step transactions, and use the encrypted number at a time to enhance their anti-CRSF token.
