Yes, kernels are a crucial part of the operating system and are responsible for managing system resources and providing a layer of abstraction between the hardware and software.
Regarding your question, it is possible for malicious code to be hidden in the kernel and remain undetected for a long time. This is known as a rootkit, which is a type of malware that is designed to hide its presence on a system by modifying the kernel or other critical system components.
One example of a rootkit is the Sony BMG copy protection rootkit, which was included on some of their music CDs in 2005. The rootkit was designed to prevent users from copying the CDs, but it also installed a hidden program that could be used by attackers to take control of the system.
Another example is the Stuxnet worm, which was discovered in 2010 and was designed to target industrial control systems. The worm used multiple zero-day vulnerabilities to infect systems and then hid its presence by modifying the kernel and other system components.
It is important to note that these types of attacks are relatively rare and are typically carried out by sophisticated attackers with specific targets in mind. However, it is still important to keep your system up to date with the latest security patches and to be vigilant for any signs of suspicious activity.
