What techniques are involved in investigating fileless malware, and how does this differ from traditional malware investigations?
Fileless malware poses a unique challenge to investigators as it operates in memory without leaving traditional file traces. Techniques involved in investigating fileless malware include memory forensics, network traffic analysis, and endpoint detection and response (EDR) tools that capture runtime behavior.
In contrast to traditional malware investigations that often involve analyzing files, registry entries, and other artifacts left on disk, investigating fileless malware relies heavily on live memory analysis and behavioral monitoring to identify malicious activities and persistence mechanisms. This approach allows investigators to uncover the steps of an attack, such as process injection, using legitimate system tools, and exploiting vulnerabilities in applications or scripts.
