New RedExt Chrome Extension Tool for Red Teamers with a Flask-based C2 Server

A sophisticated new red team tool called RedExt has recently been released, combining a Manifest V3 Chrome extension with a Flask-based Command and Control (C2) server to create a powerful framework for authorized security operations. As browser-based attack vectors continue to evolve, tools like RedExt provide valuable insights for both offensive security professionals and defenders seeking to understand and mitigate emerging threats in the browser landscape. RedExt, developed by Security researcher ShadowByte, can operate entirely within the browser context, leveraging Chrome’s extensive API capabilities while maintaining a persistent connection to its command infrastructure. The framework includes multiple data collection modules that can extract sensitive browser information, including cookies, browsing history, screenshots, clipboard contents, DOM structures, local storage data, and detailed system information. While RedExt demonstrates the potential vulnerabilities of browser extensions, it is explicitly designed for authorized red team operations and security research. Cyber Security News is a Dedicated News Platform For Cyber News, Cyber Attack News, Hacking News & Vulnerability Analysis. This innovative tool enables comprehensive browser data collection and analysis through a modern dark-themed dashboard interface. Security professionals can manage agents, assign tasks, and analyze collected data from the operator dashboard.
