Kernel Mode Code Injection

An attack that injects malicious code into the operating system's kernel.

Understanding:


Kernel mode code injection is an advanced attack technique where malicious code is injected directly into the OS kernel, allowing complete system control.

Common Applications and Use Cases:


  • Privilege Escalation Exploits – Attackers use code injection to gain kernel privileges.

  • Rootkit Deployment – Ensures deep persistence and stealth.

  • Evasion of Security Mechanisms – Undetectable by most antivirus software.

Best Practices and Security Considerations:


  • Use Kernel Patch Protection (PatchGuard) – Blocks unauthorized modifications.

  • Harden Kernel Memory Protections (DEP, ASLR) – Prevents injection attacks.

  • Perform Regular Security Audits & Integrity Checks – Detects kernel tampering.
