Why might RAM be captured during a digital forensics investigation?

• A. Detection of Encryption
• B. Detect malware
• C. Improve CPU performance
• D. Backup data before power down

Answer: (A)

Capturing RAM targets data that only exists in volatile memory, such as encryption keys and plaintext data used by active programs. In investigations, this is crucial because disk encryption keys—needed to decrypt encrypted drives or files—are often loaded into memory while the system is running. By grabbing a live memory image, you can extract those keys and access otherwise inaccessible evidence, and you can also see what encryption is in use and how it’s being handled. RAM holds other valuable artifacts too, like running processes and credentials, which help reconstruct events at the time of capture. It’s important to remember that memory is lost when power is removed, so capturing RAM must happen before powering down to preserve this data. While RAM can also reveal malware or suspicious activity, the primary and most direct reason in this context is obtaining encryption keys to decrypt evidence.
