Remotemouse considered harmful

The problem

This weekend I found a nice application to control my mac from my iPhone. It’s Remotemouse from

Unfortunately, when testing I found out that there was no pairing request nor any authentication… I just fired up wireshark to see what was happening and as expected, it’s a very dump cleartext protocol that indicates mouse gestures, clicks, and keyboard events.

I took my editor and went with this little script that connects to my mac, put the mouse on the upper right corner (over the search lense), click it and search for the terminal. Opens it and launches a bindshell.

Remotemouse is binding on all interfaces, ipv4 and ipv6, so if you’re using it and allow direct connections from the outside, you are vulnerable.

    Many thanks for this post. Maybe this is a late comment but have you tried other apps? Any recommendations?

    I did not try any alternative, so I can’t recommand any other one. Remotemouse may be just good if you disable it when you don’t use it.

    Thanks Aris. Keep on the good work.
