Problem/Question/Abstract:

Detecting Softice in W9x and NT (W2K - dunno)

Answer:

The Cracker can still defeat this protection by using FrogIce, nothing can stop SoftIce hehe. Anyway here is sum code you just instert into your Applcation.

//SoftIce in W9x

function IsSoftIce95Loaded: boolean;
var
  hFile: Thandle;
begin
  result := false;
  hFile := CreateFileA('\.SICE', GENERIC_READ or GENERIC_WRITE,
    FILE_SHARE_READ or FILE_SHARE_WRITE, nil, OPEN_EXISTING,
    FILE_ATTRIBUTE_NORMAL, 0);
  if (hFile <> INVALID_HANDLE_VALUE) then
  begin
    CloseHandle(hFile);
    result := TRUE;
  end;
end;
// SoftIce in NT OS

function IsSoftIceNTLoaded: boolean;
var
  hFile: Thandle;
begin
  result := false;
  hFile := CreateFileA('\.NTICE', GENERIC_READ or GENERIC_WRITE,
    FILE_SHARE_READ or FILE_SHARE_WRITE, nil, OPEN_EXISTING,
    FILE_ATTRIBUTE_NORMAL, 0);
  if (hFile <> INVALID_HANDLE_VALUE) then
  begin
    CloseHandle(hFile);
    result := TRUE;
  end;
end;
//to detect it
if IsSoftIce95Loaded or IsSoftIceNTLoaded then
  Application.Terminate
    {if you insert a "Nag" (Message telling him he uses SoftIce) then a amatuer cracker w'll find this protection in notime}
  //bestway of using this thing is in "project Unit"
