Cold boot attacks exploit the remanence of data in computer memory after shutdown to retrieve sensitive information. Hardware closeness entities, such as the graphics card and network card, can be exploited to access memory even when the computer is powered off. Encryption, memory scrubbing, and secure boot are essential mitigation techniques. Tools such as hardware-based memory encryption and firmware integrity verification provide robust protection. Implementing these measures is crucial to prevent unauthorized data access and maintain cybersecurity.
