    1. Russian lawmakers move to ban VPNs and Internet anonymizers — Meduza
      from Meduza
      Lawmakers from three different parties in the State Duma have submitted draft legislation to ban technologies that make it possible to circumvent Internet censorship. In the law’s explanatory note, the Duma deputies argue that Russia’s existing system to block illegal content on the Web is “not effective enough.”

    Agreed, the #WhatsApp "issue" is not a bug, it's there by design. But a designer vulnerability is still a vulnerability. https://www.eff.org/deeplinks/2017/01/google-launches-key-transparency-while-tradeoff-whatsapp-called-backdoor !crypto

    1. Google Launches Key Transparency While A Trade-Off in WhatsApp is Called a Backdoor
      from Electronic Frontier Foundation
      The Guardian ran a sensational story on Friday claiming a backdoor was discovered in WhatsApp, enabling intelligence agencies to snoop on encrypted messages. Gizmodo followed up saying it's no backdoor at all, but reasonable, intended behavior. So what's really going on here? The lost phone, lost message dilemma The issue at question is WhatsApp's answer to the question of what applications should do when someone's phone number changes (or they reinstall their app, or switch phones). Suppose Alice sends a message to Bob encrypted with Bob's key K1.

    But that re-keying attack seems like an easily fixed design flaw. The keys are already separate from the hardware, so a "clean" hardware replacement should include a transfer of key material from the old hardware to the new hardware so that re-keying queued messages is not necessary. Of course, now there's the vulnerability of exposing key material during the transfer, but that could be done requiring physical access, eg. a USB OTG cable, or Bluetooth pairing. No need to store the key material in The Cloud. !crypto
