Popular ethical hacking tricks on LAN

Birla Institute of Technology, Mesra has a large Local Area Network. Several computers are connected through hundreds of routers and switches. The local network has served several purposes whether it is file sharing through DC or organizing an online event. Such interconnection has made it vulnerable to attacks. The LAN is based on old ethernet technology. It is a good playground to practice ethical hacking. I am going to list you some working techniques that can be easily tried. I won't be telling you complete steps on how to do it. Please use it for learning purpose only.
1. Brute-force to any local website Everyone has to login to Cyberoam before they can access the fast Internet available on the ethernet. There are several automated scripts written in various languages to login to Cyberoam. Since Cyberoam is available on a local network, it is much faster to get the response for login credentials. Once the path is resolved, it takes a maximum of 5 hops for the packet to reach…

Setting up DC Hub on Raspberry Pi

Aditya Pal came to my room to check out a Raspberry Pi that I recently got as a gift. I told him, it a small credit card size computer. It powers on as soon as you plug in and boots up fast. I was already using it as a server for other purposes (hosting BitZoom). Our hostel at college had a strange network issue. The intra-hostel network worked smoothly. But, we had to face a lot of issues outside of the hostel (especially at Hostel 7 when it was disconnected from the external network for a month). The college's official DC was on the external network and it was inaccessible for quite a long time whenever we faced network issues. Aditya suggested me the idea of setting up DC on Raspberry Pi for the students of the hostel. We worked together for a few days to finally set up DC on Raspberry Pi named Raspbian. It remained active for over a year unless the college administration finally decided to shut it down due to network congestion. There were already 4 active hubs drawing traffi…

Computer Science and Engineering at Birla Institute of Technology, Mesra

I was admitted to Birla Institute of Technology, Mesra on 27th July 2015. 4 years have passed since then and I am going to share my academic experience with everyone. I hope this will help you with your college goals as well.
Semester 1
Physics - This course was the first. It explored Einstein's relativity, Dual nature of light, Maxwell's equation, Field Theory and Plasma physics. It instantly caught the attention of all my classmates. The course was lectured by Mr S.K. Rout. We used to have two-morning lectures and many slept through the class. There were 2 quizzes that were held and I scored 8/10 in both of them. An interesting thing is that most of the concepts were directly related to Intermediate Physics and so many found it easy to pick up. Others who were not well-acquainted with Integrals found in difficult.
Engineering Mathematics - This course explored trigonometric functions, approximations and integrals in details. The course was taken by Ms Sayeda Jabeen. The firs…

Hack-A-BIT 2018

A WhatsApp group named "BIT Hackathon" on 9th May 2018. It was an initiative no senior has taken to date. I was supposed to the biggest initiative ever taken by a BITian. Discussion started immediately about the name. Ayush came up with a suggestion - Hack-A-BIT. Everyone immediately accepted the name. At the same time, Ankit formed a separate group of K16 juniors to keep them updated with the Hackathon.

No work was done during the entire summer. It seemed like everyone had lost their interest in organizing the Hackathon. Finally, on 20th July, the first meeting was held. All the core members (except girls) were part of that meeting. The initial estimates of the Budget were made. All the points related to the Hackathon was noted. We could not have let the slack loose. On the same day, the core team was finalized and event details were also documented. A permission letter was drafted which was signed by the three presidents - Anuj, Aashray and Aakarshit. 

The initial event deta…
