Description
I thought that my password was super-secret, but it turns out that passwords passed over the AIR can be CRACKED, especially if I used the same wireless network password as one in the rockyou.txt credential dump. Use this 'pcap file' and the rockyou wordlist. The flag should be entered in the picoCTF{XXXXXX} format.

uhh

bro this took time, not becuase its hard but getting the rock you wordlist was not working on the kali linux wsl install i had. so i just manually downloaded it because BROO i cba if it doesnt wanna work

O.o step 1

if you wireshark the whole thing, its impossible to run through

sudo apt install aircrack-ng

this is what happens when you try to air crack without the wordlist being accessable
