Ricochet connects to the Tor network automatically.Īn already-compromised computer system will typically defeat the privacy protections that Ricochet offers, such as a keystroke logging malware.Įven though Ricochet uses Tor, other applications will not be using Tor unless the user has independently set up additional Tor services on their computer.Īctive and passive surveillance techniques can still tell if the user is using the Internet, and when, but not necessarily what they are doing on the Internet.
#Torchat portable install
Ricochet is a portable application, users do not need to install any software to use Ricochet. The use of Tor hidden services prevents network traffic from ever leaving the Tor network, thereby preserving anonymity and complicating passive network surveillance. When the user closes a conversation, the chat log is not recoverable.
There is no need to register anywhere in order to use Ricochet, particularly with a fixed server.Ĭontact list information is stored locally, and it would be very difficult for passive surveillance techniques to determine whom the user is chatting with. Message content is cryptographically authenticated and private. Ricochet does not reveal user IP addresses or physical locations because it uses Tor. Before two Ricochet users can talk, at least one of them must privately or publicly share their unique screen name in some way. A user screen name (example: ricochet:hslmfsg47dmcqctb) is auto-generated upon first starting Ricochet the first half of the screen name is the word "ricochet", with the second half being the address of the Tor hidden service. This way, Ricochet communication never leaves the Tor network. Further, using Tor, Ricochet starts a Tor hidden service locally on a person's computer and can communicate only with other Ricochet users who are also running their own Ricochet-created Tor hidden services. Ricochet is a decentralized instant messenger, meaning there is no server to connect to and share metadata with. According to Brooks, the vulnerability has been fixed in the latest release. The audit identified "multiple areas of improvement" and one vulnerability that could be used to deanonymize users. The results of the audit were "reasonably positive". In February 2016, Ricochet's developers made public a security audit that had been sponsored by the Open Technology Fund and carried out by the NCC Group in November 2015. The protocol redesign was implemented in April 2015. Zetter also wrote that Ricochet's future plans included a protocol redesign and file-transfer capabilities. On September 17, 2014, it was announced that the Invisible.im group would be working with Brooks on further development of Ricochet in a Wired article by Kim Zetter. Ricochet is a modern alternative to TorChat, which hasn't been updated in several years, and to Tor Messenger, which is discontinued.
Originally called Torsion IM, Ricochet was renamed in June 2014. A goal of the Invisible.im group is to help people maintain privacy by developing a "metadata free" instant messaging client.
