Kernel Rootkits

Malware that operates at the kernel level to evade detection and gain persistent access.

Understanding:

A kernel rootkit is a stealthy type of malware that operates at the kernel level, allowing an attacker to hide malicious processes, files, and activities from the operating system.

Common Applications and Use Cases:

Advanced Persistent Threats (APTs) – Nation-state actors use kernel rootkits for espionage.
Stealthy Malware Infections – Allows attackers to maintain long-term access.
Bypassing Security Software – Conceals itself from antivirus tools.

Best Practices and Security Considerations:

Enable Kernel Integrity Checks (e.g., Secure Boot, TPM) – Prevents unauthorized modifications.
Use Kernel Debugging & Forensics Tools – Detects hidden rootkits.
Reinstall OS if a Kernel Rootkit is Detected – Complete system compromise often requires a fresh install.
