Some simple go tools to perform a Man-in-the-middle (MITM) attack on your IMAP server in case you forgot your password.

Use case

I forgot the password to my email account, but on my iPhone Mail was still working fine. The idea is to proxy the IMAP server and retrieve the password from there.

Project structure

client is an example client for local testing (just displays the subjects of the 4 latest messages).

dns contains the CoreDNS configuration file to redirect imap.example.com to an IP in the local network.

proxy contains the IMAP proxy used to retreive the password.

server contains a test server.

Setting up

The first step is to create a self-signed certificate for imap.example.com and add it as a trusted root on the iPhone. For this purpose a website like http://www.selfsignedcertificate.com will do! To add a certificate you have to send it to your phone (with AirDrop for example), then click Install. After that go to Settings -> General -> About -> Certificate Trust Settings and flick the checkbox next to imap.example.com.

Next up is configuring the DNS. You can use sudo coredns from the dns folder and everything should work (you might have to change the local IP and domain to match your details). Then manually configure DNS on the phone to point to your server (DNS requests to other domains will be resolved/cached normally).

Now just do sudo go run proxy.go imap.example.com:993 cert.pem cert.key from the proxy folder to start the IMAP server.

Getting the password

Simply go to the Mail app and refresh. You should see the password in the IMAP proxy console!
