It contains my progress for task4 under pclub_recruitment
-
First I started with overthewire tutorials 'bandit' and 'natas' to make myself used to LINUX commands and introduce myself to Infosec.
-
Then read about sockets,telnet and buffer overflow . However I was not able to use the first two in the process .I tried to used buffer overflow in text box of chat moderation section because it was not able to hold more than 1000 characters
-
Since I had done natas, I was able to use burp suite to get into Hackers Panel but after this I was stuck.
-
what I did to get there was just changing Http error codes to 200 OK. These are two slide where changes were done.
-
I also visited /token/verify page but it didn't helped me in any progress.
-
I also tried to get shell access from terminal but it was not helpful as I couldnot get ssh private key for the server
In this course I am learning cryptography through ctf's
- First I learned modular arithmetic which is a must for RSA cryptography
- Now, i am learning AES(Advanced Encryption Standard) which is a type of symmetric cryptography
