Both challenges are kind of easy, so I decide to put their writeups together.
Description: Connect here and find the flag:
nc asis-ctf.ir 12435
After we connect to the server, it show us the following message:
Description: Find flag in this file
In each stage send the maximun size of area that can be covered by given points as a vertex of polygon in 2D.
nc 18.104.22.168 12433
mirror 1 : nc 22.214.171.124 12432
mirror 2 : nc 126.96.36.199 12434
mirror 2 : nc 188.8.131.52 12429
Points: 100 (Saw this-1), 400 (Saw this-2)
Survive and get the flag!
Note: This challenge contains two flags, one of them is easier to fetch, the other is harder.
The easier flag will be clearly indicated as "Flag 1", the harder flag as "Flag 2"
