What Is Fileless Malware?

Fileless malware performs much of its malicious activity in memory or through trusted system tools instead of depending on a conventional executable file stored permanently on disk. Certification exams may test why signature-based file scanning alone can miss this activity and why the term fileless does not mean that no files, scripts, or artifacts are ever involved. An attacker may use a malicious document, script interpreter, or administrative utility to execute code directly in memory. Behavioral detection, script logging, endpoint monitoring, application control, memory analysis, and least privilege provide stronger protection than file scanning by itself. Investigators should review process relationships, command histories, memory artifacts, scheduled activity, network connections, and legitimate tools used outside their normal operational patterns.
