What it detects

This rule detects the signed application Crysta_X64.exe loading the attacker-supplied DllXDownloadManager.dll, the DLL side-loading pair used to launch the GHOSTPULSE loader. Adversaries abuse this trusted executable to proxy execution of malicious code while evading application controls before deploying the ARECHCLIENT2 stealer.
