What it detects

This rule detects execution of dllCrt32.exe or sysCrt32.exe from the LOCALAPPDATA Microsoft WindowsApps directory, the dropped stealer binaries Red Canary attributed to dllFake trojanized installers that share code with SecondEye. These named executables in the WindowsApps path are not legitimate Store aliases, so their execution indicates a data-stealing implant staged for credential and clipboard theft.
