🕵️♂️ Red Teams Exploit Microsoft Text Services Framework for Stealthy Persistence. Praetorian Labs has identified a novel persistence technique utilizing the Microsoft Text Services Framework (TSF), which allows for stealthy code injection into various high-value processes without raising alarms. Although administrative privileges are required to register new TSF plugins, this method enables attackers to maintain access to compromised systems by injecting code into applications like web browsers and task managers. The article outlines the registration process, potential indicators of compromise, and detection techniques, emphasizing the need for defenders to enhance their security measures against this obscure yet effective persistence mechanism. Understanding TSF’s capabilities is crucial for both red teams and defenders in the cybersecurity landscape.
