Memory-Only Malware: Hunting Threats That Never Touch Disk
Fileless malware executes entirely in memory, leaving no binary for file-based scanning to find. PowerShell cradles, .NET reflection loading, shellcode injection, and process hollowing are all fileless techniques. This is how to detect execution that never touches disk.

WMI Persistence: Subscriptions That Survive Reboots and Evade Almost Every Checklist
WMI event subscriptions provide persistent code execution triggered by system events. They survive reboots, are stored in the WMI repository rather than the filesystem, and are invisible to most persistence checklists. This covers the technique, multiple variants, and detection.
