'Detects and analyzes fileless malware that operates entirely in memory

When to use

• EDR alerts indicate suspicious behavior from trusted system binaries (PowerShell, mshta, wmic, regsvr32)
• Investigating attacks that leave no traditional malware files on disk
• Analyzing WMI event subscriptions, registry-stored payloads, or scheduled task abuse for persistence
• Building detection rules for LOLBin (Living Off the Land Binary) abuse in enterprise environments
• Memory forensics reveals malicious code but no corresponding files exist on the filesystem

When not to use

• traditional file-based malware
• standard static and dynamic analysis methods for disk-resident malware
