I just noticed that Cryptomator 1.5.8-0ppa1 listens on a high-numbered port on all network devices:
tcp6 0 0 :::34949 :::* LISTEN 14414/cryptomator
This does not seem to be an officially assigned service address.
I can successfully connect to this port using telnet, but there’s no incoming data and if I enter random stuff, the connection is dropped by Cryptomator.
Open ports accessible via network can always be a potential security issue, so I’d like to know what it’s used for and if it can be disabled or made to listen on
