Skype finalizes its move to the cloud, ignores the elephant in the room | Ars Technica. This article describes the move, by Microsoft, of Skype away from peer to peer communications to a cloud based system. The peer to peer system, instead of being private, was vulnerable to third party denial of service attacks, and exposure of IP addresses. However, the peer to peer network required always connected computers, and that isn't the way most of us operate. In the transition, Microsoft created SuperNodes which it maintained; but, now, the system is moving to a dedicated cloud server network that Skype clients will connect to. The problem is that the new service is not transparent, and the communications can't be encrypted. End to end encryption is becoming the only way to conduct safe communications and be relatively secure in the privacy of the communications. Competing services, like Facebook Messenger, WhatsApp, and iMessage are offering end to end encryption to anyone who wants it. Until Microsoft does the hard work of making Skype secure, lawyers should not trust confidential communications to it.
