Which of the following is an example of memory injection?

Rationale

Malicious code is copied to the allocated space of an already running process.

Memory injection occurs when an attacker injects malicious code into the memory of a running process, allowing it to execute within the context of that process. This technique often exploits vulnerabilities in applications to manipulate their behavior or gain unauthorized access.

A (Two processes access the same variable, allowing one to cause a privilege escalation.) YOUR ANSWER

This describes a race condition or shared resource vulnerability rather than memory injection. While it can lead to privilege escalation, it does not involve directly inserting code into the memory space of a process, which is the hallmark of memory injection techniques.

B (A process receives an unexpected amount of data, which causes malicious code to be executed.) YOUR ANSWER

This scenario is more indicative of a buffer overflow attack where excessive data leads to code execution. However, it doesn't specifically refer to the act of injecting code into a running process's memory, which characterizes memory injection.

D (An executable is overwritten on the disk, and malicious code runs the next time it is executed.) YOUR ANSWER

This situation involves modifying the executable file itself rather than injecting code into a running process's memory. While it represents a method of deploying malware, it lacks the direct manipulation of a process's memory space that is essential to memory injection.

Conclusion

Memory injection is a critical technique in cyber attacks, allowing malicious actors to execute code within the context of legitimate processes. Among the provided choices, option C accurately reflects this concept, as it involves the direct copying of malicious code into the memory of an already running process. The other options describe different types of vulnerabilities or attack vectors that do not encompass the essence of memory injection.
