Yes, we have a plan to release WhiteEgret v4 patch with a WEUA sample of access control for script programs.
The latest WhiteEgret cannot control script programs since script files read by an interpreter are not hooked by the execve system call.
We consider that script programs can be controlled by controlling the files inputted by interpreters, accordingly.
We consider that the control can be realized using the read system call hooking.
Now, we are developing WhiteEgret with the read system call hooking and WEUA which controls the script files to be read to interpreters using information from the read system call hooking and white list.

Hi,
regardling the last one, do you have a plan for handling it?
