+## AKA
+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.
+
+<img src="ls.png">
+
+
+#### Step-2:
+So I tried `base64 flag.txt | base64 -d`, and luckily worked.
+
+<img src="Flag.png">
+
+Voila! We have our flag.
+
+#### Step-2:
+Finally the flag becomes:
+`csictf{1_4m_cl4rk3_k3nt}`

+## HTB 0x1
+The main idea finding the flag is anonymous FTP bypass.
+
+#### Step-1:
+The idea is similar to getting root access of a machine. So I started with basic `nmap 34.93.37.238` scan on the server. But unfortunately, not much. 
+
+#### Step-2:
+So I random access on FTP server through the given IP address by `ftp -p  34.93.37.238 5001`.
+
+Voila! I was in!
+
+No idea of credentials though.
+
+#### Step-3:
+So I just tried to access the FTP page through URL: ftp://34.93.37.238:5001/
+
+It directly showed this webpage.
+
+<img src="Web1.png">
+
+#### Step-4:
+
+Next it was just navigating through to get the flag.
+

+#### Step-5:
+Finally the flag becomes:
+`csictf{4n0nym0u5_ftp_l0g1n}`

+## Where am I
+The main idea finding the flag is anonymous FTP bypass.

+#### Step-1:
+I had to follow this because following `id_rsa` is not helping me bypass to root.

+## find32
+The main idea finding the flag is using basic Linux commands.
+
+#### Step-1:
+When we run `ssh user1@chall.csivit.com -p 30630` and password as `find32`, we are pwned into a shell.
+
+A simple `ls` command gives us many files which are random.

+#### Step-2:
+So I tried `grep -R {`, to search for possible flags throughout.
+
+<img src="grep1.png">
+
+#### Step-3:
+Well, I was greeted with a false flag & new user credentials, so I ssh'ed with that next time.
+
+`ssh user2@chall.csivit.com -p 30630` and password as `AAE976A5232713355D58584CFE5A5`. This weird ass number beside User2 name.
+
+Luckily I was in.
+
+#### Step-4:
+
+This time I tried `ls` and actually find very less files. 
+
+<img src="ls.png">
+
+#### Step-5:
+
+So I immediately tried `grep -R _` and got it.
+
+<img src="Flag.png">
+
+#### Step-3:
+Finally the flag becomes:
+`csictf{th15_15_unu5u41}`
