***Disabling CTRL-ALT-DELETE on Windows NT, Windows 2000, and Windows XP*** There is an undocumented way to disable the Ctrl Alt Del key sequence on Windows NT/2000/XP using the registry. The key, 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon : AutoAdminLogon (REG_SZ)' has only two legal values, according to Microsoft: "0" and "1". 0 disables automatic logon of the account stored, and 1 enables it.

With NTFS partitions, intruders can hide their toolkits behind a 'front file'. Explorer and DIR only show the front file and the size of the front file, leaving no clue as the hidden 'back streamed' files. This code finds them. You can back stream a file like this "copy MyTrojanProgram.exe SomeSystemFile.ini:MyTrojan.exe" SomSystemFile.ini will stay the same size and the backstreamed trojan will be almost undetectable.

This is an example how easy it is to manipulate the execution flow of an Pe-file (.exe) This little tool will patch a given file, to run the command 'cmd'. This example is not really usefull but as you can imagine that it is also posible to start a backdoor very stealth with this technic. How it works: 1. it will search for the last section of the exe 2. the it will search in the last section where are 69 NULL-bytes to paste your execution code 3. then it start to search for the position in the exe where the first 5 bytes of the code are. 4. save the bytes which will be overwritten (how much it will be u can define with the offset) 5. it will overwrite the bytes with a jump (E9) to the execution-code 6. generate the execution code thst it will look like this NOP + static code + WinExec address + saved bytes + back jump address 7. paste the exeution code at the postion of 2. End For question about this code please mail me.
