The main idea finding the flag is using base64 command.

Step-1:

When we run nc chall.csivit.com 30611, we are pwned into a shell. I tried some basic commands like ls to find flag, but it is blocked.

Step-2:

So I tried base64 flag.txt | base64 -d, and luckily worked.

Voila! We have our flag.

Step-2:

Finally the flag becomes: csictf{1_4m_cl4rk3_k3nt}
