Know the ToxIDs of your Tox friends to be able to impersonate them to you.This means, to exploit this vulnerability in practice, someone not only needs to successfully steal your private key, but additionally: But because of the KCI vulnerability, they may also be able to impersonate others to you. It is clear that someone who stole your identity is able to impersonate you. Now in this case the KCI vulnerability leads to “interesting” behavior.
