Software Extentions: IDE extentions

Threat Actors may abuse an integrated development environment (IDE) extension to establish persistent access to victim systems. IDEs such as Visual Studio Code, IntelliJ IDEA, and Eclipse support extensions - software components that add features like code linting, auto-completion, task automation, or integration with tools like Git and Docker. A malicious extension can be installed through an extension marketplace (i.e., Compromise Software Dependencies and Development Tools) or side-loaded directly into the IDE.
