NEW QUESTION # 154
A forensic examiner is investigating possible malware compromise on an active endpoint device. Which of the following steps should the examiner perform first?
- A. Verify the hash value of the image with the value of the copy.
- B. Use a write blocker to create an image of the hard drive.
- C. Create a memory dump from RAM.

- E. Download and apply the latest AV signature.
Answer: C
Explanation:
A memory dump is a snapshot of the contents of the random access memory (RAM) of a system at a given point in time. A memory dump can provide valuable information for a forensic examiner who is investigating possible malware compromise on an active endpoint device, such as running processes, open files, network connections, encryption keys, or malware artifacts. Creating a memory dump from RAM should be the first step that the examiner performs, as it preserves the volatile data that could be lost or altered if the system is powered off or rebooted1.
