Hi everyone,
Came across this the other day and I wanted to share.
Santoku Linux is a specially designed Linux distro based off of Lubuntu that has a lot of pre-packaged tools for doing mobile forensics, security analysis, and malware analysis. Think of it like Kali, but for your cellphone.
https://santoku-linux.com/They also have a How-To page on there that can get you started.
I haven't had a chance to play with it in depth yet, but it looks like the majority of the tools are for Android. However, they (the company behind it, NowSecure) say there's a lot of support for iOS coming.
Happy hunting!
