What detection and interception methods are recommended against the virtual-disk-based fileless technique?
Since the technique relies on loading the `imdisk.sys` driver, monitoring for unfamiliar driver installations or loading events is key. Security solutions should track `sc start` or `cliramidisk.exe i` commands and block unsigned or suspicious drivers. Additionally, behavioral analysis can flag the creation of RAM disks (e.g., via `imdisk -a` commands). These measures, combined with endpoint detection and response (EDR) rules, can effectively intercept such attacks, similar to techniques outlined in stealth execution discussions.
