I still miss my college days. Our crappy IT Dept restricted internet usage on campus. Each student used to get 10 GB of internet data and they used Cyberoam for login (without HTTPS). 10 GB was so less (at least for me).

Now, thanks to CS50, I learned that HTTP was not secure and somehow you can access login credentials. I spent a night figuring things out and then bam!! Wireshark!!!!

I went to the Central Library and connected using Wireshark. Within a matter of minutes, I got more than 30 user ids and passwords. One of them belonged to a Professor. And guess what, it had unlimited data usage with multiple logins. I felt like I was a millionaire. On my farewell, I calculated how much data I used. It was in TBs.

Lesson: Always secure your URLs.
