Malicious JavaScript is a type of code that is designed to perform malicious actions on a victim’s computer or device. It can be used to steal sensitive information, manipulate web content, or perform other malicious activities. The detection of malicious JavaScript is an important task for protecting against cyber threats, as it can help to identify and prevent attacks before they can do harm. There are a variety of techniques that can be used to detect malicious JavaScript, including static analysis, dynamic analysis, and machine learning-based approaches. Static analysis involves analyzing code without executing it, while dynamic analysis involves executing the code and observing its behavior. Machine learning-based approaches use algorithms to analyze code and identify patterns that may indicate malicious intent. By using these and other techniques, organizations can effectively detect and prevent attacks that involve malicious JavaScript.
