# Quickmaths
the server literally just gives u 1000 math questions one after other such as `a+b`. so we use python to implement a script to connect to the server and do the maths for us. after solving 1000 questions in a row u get a flag
cool thing is that the server sends the questions formatted in a way that running `eval()` on what it sends will give us the answer in python
however, running `eval()` is dangeroustherefore i suggest future organisers use this same challenge but send a reverse shell at the end to hack the competitorsyou thought you were here to hack us, but we were here to hack you! - future organisers hopefully
solve```py#nc 34.148.103.218 1228
import telnetlibfrom string import ascii_lowercase as ab
HOST = "34.148.103.218"PORT = 1228
tn = telnetlib.Telnet(HOST, PORT)print(tn.read_until(b"\n"))print(tn.read_until(b"\n"))print(tn.read_until(b"\n"))print(tn.read_until(b"\n"))
for i in range(0, 1000):    print(tn.read_until(b"\n"))    q=tn.read_until(b"\n").decode()    ans=str(eval(q)) #hope the server did not send a reverse shell script    print(q)    print(ans)    tn.write(bytes(ans, "utf-8")+b"\n")    print(i)
tn.interact() #idk if this was needed```
it timed out a few times then i complained to the admins who said the challenge creator was offline. so i just ran it a few times until it stop disconnecting and worked
