Execution with Explicit Credentials via Scripting
editExecution with Explicit Credentials via Scripting
editIdentifies execution of the security_authtrampoline process via a scripting interpreter. This occurs when programs use AuthorizationExecute-WithPrivileges from the Security.framework to run another program with root privileges. It should not be run by itself, as this is a sign of execution with explicit logon credentials.
