detecting-fileless-attacks-on-endpoints
Detects fileless malware and in-memory attacks that execute entirely in RAM without writing persistent files to disk, evading traditional antivirus. Use when building detections for PowerShell-based attacks, reflective DLL injection, WMI persistence, and registry-resident malware. Activates for requests involving fileless malware detection, in-memory attacks, PowerShell exploitation, or living-off-the-land techniques.

# Detecting Fileless Attacks on Endpoints
## When to Use
Use this skill when:
- Building detection rules for fileless malware that operates entirely in memory
- Hunting for PowerShell-based attacks, reflective DLL injection, and WMI abuse
- Configuring endpoint telemetry (Sysmon, AMSI, PowerShell logging) to capture fileless indicators
- Investigating incidents where traditional AV found no malicious files
**Do not use** for detecting file-based malware or for malware reverse engineering.
## Prerequisites
- Sysmon with process creation and WMI event logging enabled
