Memory injectionoccurs whenmalicious code is written into the memory space of a running process, allowing it to execute without writing anything to disk. This is often used infileless malware attacks, making detection harder.
* A (privilege escalation)describes a race condition, not memory injection.
* B (unexpected data causing execution)describes abuffer overflow attack, not memory injection.
* D (overwriting an executable)is apersistence technique, but it is not an example of in-memory injection.
