Memory forensics focuses on analyzing volatile memory. Which artifacts can RAM reveal?

• A. Running processes, network connections, encryption keys, and malware behavior
• B. Archived emails on disk
• C. Printer logs
• D. BIOS settings

Answer: (A)

Volatile memory holds the live state of a running system, so memory forensics zeroes in on artifacts that exist in RAM while the machine is on. Running processes show up in memory as the actual programs currently executing and their related resources, which you can enumerate to see what’s active at that moment. Open network connections are also kept in RAM, including which sockets are in use and the state of those connections, so you can map current communications and infer what the system was doing online. Encryption keys and other key material may reside in memory during active sessions or when apps decrypt data on the fly, making RAM a prime source for recovering sensitive keys that aren’t stored securely elsewhere. Malware behavior often leaves traces in memory—loader code, injected modules, hooks, and other memory-resident artifacts that reveal how malware operates in real time even if it’s not written to disk. Artifacts like archived emails on disk aren’t typically found in RAM because they live on non-volatile storage and would only appear in memory if a program loaded them into memory for viewing. Printer logs and BIOS settings are also stored outside of volatile memory: printer logs are usually kept on the printer or a print server, and BIOS settings live in firmware or non-volatile storage, not in a snapshot of RAM.
