Patches imm32.dll so that it calls another netxxxxx.dll file when Winlogon loads it. If you try to delete the netxxxx.dll file you will get missing DLL errors on every executable you run while Windows loads. Target replacing the imm32.dll file and you are good.

Hi,

thanks for the sample.

Is the any dropper available also?

Thanks.

Pulled it from an infected machine after other scanners were already run but failed on this one. I have no dropper at this time sorry.
