Its notable features include bypassing application whitelisting through InstallUtil.exe, utilizing a recursive DNS tunnel to retrieve encrypted commands, and maintaining a small footprint on both memory and network resources. The tool leverages a DLL that periodically polls a DNS TXT record for remote instructions, allowing operators to execute various payloads, such as spawning a reverse shell, while potentially evading detection.
