Hijack Execution Flow: AppDomainManager, Sub-technique T1574.014 - Enterprise | MITRE ATT&CK® (opens in new tab)

Adversaries may execute their own malicious payloads by hijacking how the .NET AppDomainManager loads assemblies. The .NET framework uses the AppDomainManager class to create and manage one or more isolated runtime environments (called application domains) inside a process to host the execution of .NET applications. Assemblies (.exe or .dll binaries compiled to run as .NET code) may be loaded into an application domain as executable code.[1]
