This post is about how me and Avijit retrieved multiplie cyberoam username/password combinations using python. This also highlights how vulnerable the system is if you are not using a more secure password . Even the default password given to us by the College are being recycled for many years.


Before you read this, I want to clarify that we do not intend to use our findings in any unethical way. No username-password combinations will be disclosed. The purpose of writing this blog was to notify possible victims to prevent their ID from being used by someone else.

What is Cyberoam ?

Its a network gateway software which requires students to login to use the internet.

How we did it ?

I wrote a simple python script which basically sends multiple requests to the server with varying username & password combinations. It checks whether the combination is correct and if it is correct , the combination is stored in a file. I wrote that script to iterate over 2000 users and check 16 passwords, basically sending around 32,000 requests.

How we got the usernames ?

It was simple. The college keeps a record of the marks obtained by the students with their enrollment number(username) and keeps it in the file-server (which is open to all the students).

Avijit did a little search around and was able to compile a list of all the 1st year students by going through the data available in different department’s servers.

How we got the passwords ?

We found out that the default passwords given by the college have a pattern, also the same passwords( a set of around 150–300 passwords) were being used every year. So we asked around and compiled a list of those passwords for our script. We could acquire around 10 passwords out of those.

Running the script

A Screenshot of the script in action

Before running the script we didn’t have any high hopes, but on executing it, the outcome surprised us. We managed to get 62 combinations.

Its sad to see that our user IDs are so easy to crack.


Our College uses Cyberoam. They control and monitor what we see and what we do not on the Internet. They give us a very very crappy speed for a Computer Science College. They block even the most harmless sites like IMDb.

The least they can do is to add some security. I am tired of hearing my other friends praising their college’s internet speed, saying how they can download a movie in minutes , where as I can’t even download online lectures without exceeding my limited quota.
