Shellcode Injection

What is Shellcode Injection?

Shellcode Injection is a technique where attackers inject and execute malicious code (shellcode) into a target process. This allows them to gain control of the system, escalate privileges, or perform other malicious activities.

How Shellcode Injection Works

Shellcode Injection typically involves the following steps:

• Vulnerability Identification: Identify a vulnerability that allows code execution, such as a buffer overflow.
• Shellcode Creation: Develop shellcode to perform the desired malicious activity.
• Injection: Inject the shellcode into the target process's memory.
• Execution: Execute the shellcode to gain control of the system.

How to Defend Against Shellcode Injection

To protect your systems from Shellcode Injection, follow these best practices:

• Patch Vulnerabilities: Regularly update software and systems to fix known vulnerabilities.
• Use DEP and ASLR: Enable Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) to mitigate shellcode injection.
• Monitor for Anomalies: Use tools like SIEM and EDR to detect unusual activity.
• Conduct Penetration Testing: Regularly test your systems for vulnerabilities and address them promptly.
