Elastic describes SADBRIDGE as a loader distributed inside an MSI executable that combines DLL side-loading with a range of injection methods to run its malicious payloads. It misuses trusted programs such as x64dbg.exe and MonitoringHost.exe to side-load rogue DLLs like x64bridge.dll and HealthServiceRuntime.dll, which in turn launch later stages and shellcode.
