### Common JavaScript Vulnerabilities and Their Exploit Times Here’s a list of common ways to hack JavaScript applications, along with a rough estimate of how long each attack might take to successfully steal information: - **Cross-Site Scripting (XSS)** - **Time to Execute**: Seconds to minutes - **Description**: Injecting malicious scripts into webpages, enabling data theft from users interacting with the compromised page. - **Cross-Site Request Forgery (CSRF)** - **Time to Execute**: Seconds to minutes - **Description**: Tricks a user into executing unwanted actions on a different site while logged in, leading to unauthorized transactions or data changes. - **JavaScript Injection** - **Time to Execute**: Seconds to minutes - **Description**: Injecting custom JavaScript code into a vulnerable web application can allow attackers to execute any code on the user's browser. - **Session Hijacking** - **Time to Execute**: Minutes - **Description**: Exploiting session tokens or cookies to gain unauthorized access to user accounts, potentially taking over accounts. - **Phishing Attacks** - **Time to Execute**: Minutes to hours (depending on complexity) - **Description**: Creating fake web pages to steal user credentials, commonly through deceptive links or pop-ups. - **Remote Code Execution (RCE)** - **Time to Execute**: Minutes to hours (depending on system) - **Description**: Executing arbitrary code on the server or client, which can lead to full control of the system. - **Local Storage Attacks** - **Time to Execute**: Seconds to minutes - **Description**: Accessing sensitive information stored in the client’s local storage through XSS vulnerabilities. - **Clickjacking** - **Time to Execute**: Seconds to minutes - **Description**: Trick users into clicking on something different from what they perceive, potentially leading to action execution without consent. - **Man-in-the-Middle (MitM) Attacks** - **Time to Execute**: Minutes (requires setup) - **Description**: Intercepting communication between the user and a website to capture sensitive data, often using insecure connections. - **Data Breaches via APIs** - **Time to Execute**: Minutes to hours (depending on discovery of vulnerability) - **Description**: Exploiting insecure APIs can allow attackers to gain unauthorized access to data or functions. Each of these vulnerabilities has varying degrees of complexity and attack vectors, and their impact can be severe, especially in web applications handling sensitive information. Developers must prioritize security to mitigate these vulnerabilities effectively.
