I have an iPhone 5s jailbroken (obviously) and I'm trying to learn network hacking and password sniffing. I installed pirni-derv and have everything running correctly. My only problem is, upon derv saying it has captured the plaintext passwords used to log into websites, it says it stores them in a file called pw.txt. I figured this file would be located under /var/mobile like the rest of the files that run pirni-derv, however it isn't. I even tried creating a new text file located in /var/mobile titled pw.txt for derv to dump the passwords, however, it doesn't work. Does anyone know where the correct pw.txt file is located, and if not, how can I recode derv to dump snatched passwords into the newly created pw.txt file? I've been trying to fiqure this out for about a week now, but I seem to be stuck:/
