What is the more stealthy method introduced in this article, and how does it deceive system administrators?

The more stealthy method places the null byte in the middle of a registry value name, such as `test2\0abc`. When viewed in `regedit.exe`, the name is truncated at the null byte, so it appears as `test2`. If a legitimate key named `test2` also exists, both appear identically in the registry editor, but the hidden key actually stores different data (e.g., `hidden0123456789abcdef` instead of `0123456789abcdef`). This provides greater deception than the leading-\0 method because it produces no error messages.
