Everspin Unveils 'MTD-RTAS' Solution for Financial App Security

2025.09.02

Everspin announced on the 2nd that it has unveiled a security solution based on MTD (Moving Target Defense) and RTAS (Real Time Threat Alarm Service) to strengthen financial app security. The company explained that this is an alternative approach at a time when domestic and international financial institutions still rely on basic operating system (OS) APIs vulnerable to hooking. According to Everspin, traditional financial app security has relied on system APIs accessible by any developer. Using hooking tools like reverse engineering tools (Frida), bypass is possible without analyzing security modules. Consequently, there have been constant pointing out that even low-level attackers can threaten financial app security. To supplement this, Everspin operates the MTD-based security solution 'Eversafe.' Eversafe improved security by using system call (Syscall)-based security codes instead of system APIs and applying a structure that periodically transforms them. Additionally, RTAS is designed so that it cannot be neutralized unless an attacker simultaneously tampers with all financial apps installed on a device through a mutual protection system between financial apps. This system is based on 'FakeFinder,' the malicious app detection technology held by Everspin. It is currently applied to apps of about 60 major domestic financial institutions, protecting a cumulative total of approximately 43 million terminals. Based on this, RTAS provides services by building a joint defense network between financial apps. MTD-based security is drawing attention as a next-generation security method overseas, and many startups mainly in the U.S. and Europe are continuing research. Everspin explained that it has secured technical and legal competitiveness by registering 36 patents in 12 countries, including Korea, the U.S., Japan, Europe, and China. Currently, major domestic banks and brokerage firms are implementing this solution to strengthen security levels, and there is a trend of expansion into overseas financial institutions such as in Japan and Southeast Asia. Everspin CTO Seong-wook Yoon stated, "The multi-layered security system combining MTD and RTAS is intended to provide a more stable environment for financial app users. We will continue to raise the level of mobile security in cooperation with domestic and international financial institutions."
