The content of the document, which may be hard to read due to some font rendering issues, is also available in the table below. While the document confirms that the FBI can't gain access to encrypted messages sent through some services, the other type of information they can glean from providers might still help authorities in other aspects of their investigations. The document, obtained earlier this month following a FOIA request filed by Property of the People, a US nonprofit dedicated to government transparency, appears to contain training advice for what kind of data agents can obtain from the operators of encrypted messaging services and the legal processes they have to go through.ĭated to January 7, 2021, the document doesn't include any new information but does a good job at providing an up-to-date summary of what type of information the FBI can currently obtain from each of the listed services.Īs Forbes reporter Thomas Brewster said on Twitter earlier this week, past news reports have already exposed that the FBI has legal levers at its disposal to obtain various types of personal information even from secure messaging providers that often boast about providing increased privacy to their users. Zoom Rooms and Zoom phone participants will be able to attend if explicitly allowed by the host.FBI document shows what data can be obtained from encrypted messaging appsĪ recently discovered FBI training document shows that US law enforcement can gain limited access to the content of encrypted messages from secure messaging services like iMessage, Line, and WhatsApp, but not to messages sent via Signal, Telegram, Threema, Viber, WeChat, or Wickr. Unlike current Zoom’s encryption, this will not support phone bridges, cloud recording or non Zoom conference room systems. We are also investigating mechanisms that would allow enterprise users to provide additional levels of authentication. The cryptographic secrets will be under the control of the host, and the host’s client software will decide what devices are allowed to receive meeting keys, and thereby join the meeting. This key will be distributed between clients, enveloped with the asymmetric keypairs and rotated when there are significant changes to the list of attendees. An ephemeral per-meeting symmetric key will be generated by the meeting host. Logged-in users will generate public cryptographic identities that are stored in a repository on Zoom’s network and can be used to establish trust relationships between meeting attendees. This is how Zoom explains the technology: Zooms says that in the future, they will offer an end to end encrypted meeting mode to all paid accounts. However, some features require Zoom to keep encryption keys in the cloud, like adding a phone bridge or use in-room meeting systems. The encryption keys are generated by Zoom’s servers. This is not decrypted until it reaches the recipient’s devices. Zoom says their current encryption involves encryption at each sending client device. Keybase was a key directory that mapped social media identities to encryption keys as well as offering and end to end encrypted chat called Keybase Chat.
