Memory forensics is the analysis of a system’s volatile RAM to find evidence that may not exist on disk. Investigators capture memory from a live machine and inspect running processes, loaded modules, network connections, injected code, decrypted configuration, command history, and cryptographic material such as session keys or passwords. Because RAM changes constantly, it can reveal what malware was doing at the moment of capture.
In cyber security, memory forensics matters because many intrusions leave only limited disk artifacts. Fileless malware, process injection, in-memory loaders, and some remote access trojans can hide their behavior after execution. For defenders, memory analysis helps confirm compromise, recover attacker commands, and identify tools that static antivirus scans miss. It is especially useful against Golang malware and other statically linked binaries, where runtime behavior may be easier to spot in memory than on disk. In practice, memory forensics often complements endpoint telemetry, helping analysts connect suspicious file access, share activity, and live command execution to a real attack.
