bat in invisible mode

Running .BAT or .CMD files in invisible mode

Windows Script Host’s Run Method allows you run a program or script in invisible mode.

Sample Code

Set WshShell = CreateObject("WScript.Shell")
WshShell.Run chr(34) & "C:\Batch Files\syncfiles.bat" & Chr(34), 0
Set WshShell = Nothing

Copy the lines above to Notepad and save the file with .VBS extension. Edit the .BAT file name and path accordingly, and save the file. Double-click the .VBS file to run it.

(Ref: Run Method. Setting intWindowStyle parameter to 0 hides the window)

bat file

This is a memory resident parasitic BAT-file infector. It's easier to show the text of the virus than to say something about its algorithm. The virus text is very simple:

REM <<< code: jmp installation, int_21 handler part 1 >>>
copy %0>nul
rem <<< code: TSR installation, int_21 handler part 2 >>>

Note: the brackets <<< >>> mean that here is the non-text bytes of the virus.

The main feature of this virus consist in its double-facing. The virus body is executed in two formats: it's executed as batch file if the infected file has BAT extension, or as COM file it the file has COM extension.

On running this virus from BAT file it copies itself (i.e. host file) into the new temporary file B.COM by using the DOS command

copy %0

The %0 parameter substitutes by the name of the batch file as it typed at the command prompt. This way the virus creates the copy of infected BAT-file with COM extension. Then this virus executes that file by next line of BAT file and then deletes it from disk. The binary code and data of the virus are remarked my REM command and do not influence on BAT virus flow.

The B.COM file is executed as a standard COM file. By this the text strings of the file beginning


are interpreted as 'dummy' i8086 instruction like these:

INC register
DEC register
OR register, immediate
AND register, register

These instructions do not influence on COM program execution (as the remarked binary code do not used by BAT variant of this virus). After execution of the last text bytes (REM instruction of the second line of BAT virus) the virus activation code starts to work.

The algorithm of virus installation is very primitive, it's occupies ten assembler instruction only. The virus hooks INT 21h by using standard DOS functions GETVECT and SETVECT (AX=3521h, 2521h) and then stays memory resident by using INT 27h. The virus do not checks the memory for the presence of the TSR part of previous execution. So the virus will present in memory so many times as the infected BAT-files are executed.

The virus intercepts one DOS function only, it's WRITE HANDLE function (INT 21h, AH=40H). The virus checks the beginning of write buffer for the '@echo' string and if that string is present the virus write itself body before saving that buffer. A lot of BAT-file contains that string at their beginnings so they will be infected upon creating, copying or modifying.

So the virus write itself into the BAT-file beginning. The infected files at first create the B.COM file, run and delete it and then they are continued as they are not infected.

How To: Change Your Ip In Less Then 1 Minute

1. Click on "Start" in the bottom left hand corner of screen
2. Click on "Run"
3. Type in "command" and hit ok

You should now be at an MSDOS prompt screen.

4. Type "ipconfig /release" just like that, and hit "enter"
5. Type "exit" and leave the prompt
6. Right-click on "Network Places" or "My Network Places" on your desktop.
7. Click on "properties"

You should now be on a screen with something titled "Local Area Connection", or something close to that, and, if you have a network hooked up, all of your other networks.

8. Right click on "Local Area Connection" and click "properties"
9. Double-click on the "Internet Protocol (TCP/IP)" from the list under the "General" tab
10. Click on "Use the following IP address" under the "General" tab
11. Create an IP address (It doesn't matter what it is. I just type 1 and 2 until i fill the area up).
12. Press "Tab" and it should automatically fill in the "Subnet Mask" section with default numbers.
13. Hit the "Ok" button here
14. Hit the "Ok" button again

You should now be back to the "Local Area Connection" screen.

15. Right-click back on "Local Area Connection" and go to properties again.
16. Go back to the "TCP/IP" settings
17. This time, select "Obtain an IP address automatically"
tongue.gif 18. Hit "Ok"
19. Hit "Ok" again
20. You now have a new IP address

With a little practice, you can easily get this process down to 15 seconds.

This only changes your dynamic IP address, not your ISP/IP address. If you plan on hacking a website with this trick be extremely careful, because if they try a little, they can trace it back
