What is CSRF (Cross Site Request Forgery)

Cross-Site Request Forgery (CSRF) attacks are a significant cyber threat that deceive users into performing unintended actions on authenticated web applications. These attacks exploit the user's existing session credentials to execute unauthorized actions, such as transferring funds or changing account settings, without the user's knowledge. To prevent CSRF attacks, several techniques can be employed, including the Double Submit Cookie approach, Anti-CSRF tokens, and the SameSite Cookie Attribute, each offering varying degrees of security and complexity. An example of a tool addressing CSRF vulnerabilities is SuperTokens, an open-source library that enhances web application security by implementing robust anti-CSRF measures like the Strict SameSite Cookie Attribute. These strategies, along with secure authentication practices, are crucial for maintaining the integrity and security of web applications, ensuring that online transactions remain safe and trustworthy.
