CompTIA Security+ (SY0-701) — Question 454

Which of the following is an example of memory injection?

Answer options

• A. Two processes access the same variable, allowing one to cause a privilege escalation.
• B. A process receives an unexpected amount of data, which causes malicious code to be executed.
• C. Malicious code is copied to the allocated space of an already running process.
• D. An executable is overwritten on the disk, and malicious code runs the next time it is executed.

Correct answer: C

Explanation

The correct answer, C, describes how malicious code is inserted into the memory space of a running process, which is the essence of memory injection. Option A concerns privilege escalation through shared variables, option B addresses buffer overflow leading to code execution, and option D refers to a disk-based infection method, none of which directly illustrate memory injection.
