Does this actually pose a threat to LN authentication e.g. here on SN? When you repeatedly sign login authentication messages with your node privkey and hand them to SN, aren't you opening up this attack vector?
The signature used is not broadcast so not unless it's compromised.
I'm quite dubious about this attack on ECDH but I'm watching for more info if there is any.
