A GPU (Graphics Processing Unit) is a specialized computer chip designed to rapidly process and render images, videos, and animations. Originally developed to accelerate graphics tasks in gaming and professional applications, GPUs are now widely used in fields like artificial intelligence, scientific computing, and cryptocurrency mining due to their ability to handle many tasks at once. In cybersecurity, GPUs can sometimes be leveraged by malware to perform complex computations or evade detection by offloading suspicious activities from the main processor.
