    Hi, members of my !threema group. As GNUSocial.de is unfortunately shutting down, this group will be lost. As I switch to Mastodon I also cannot keep this group anymore.

    So what to do?
    1. Anyone at GNUSocial.de: You have to migrate away, anyway.
    2. You can follow me personally at https://social.wiuwiu.de/@rugk. I'll of course also tuut about #Threema.
    3. You can also pin hashtags on Mastodon to stay up-to-date and follow all the whole hashtag.

    BTW, the news just going around the group chat vulnerabilities in major crypto protocol were public in July 2017 (see my own summary below; which is still valid AFAIK). Good explanation on https://www.wired.com/story/whatsapp-security-flaws-encryption-group-chats/

    Seems news outlets need talks (RealWorldCrypto in Swizerland) to notice such things… :)
    And authors seem to revised their paper in 2018, too.

    1. WhatsApp Flaws Could Allow Snoops to Slide Into Group Chats
      from WIRED
      German researchers say that a flaw in the app's group-chat feature undermines its end-to-end encryption promises.
    2. File without filename could not get a thumbnail source.

      More is Less: How group chats weaken the security of instant messengers #Signal, #WhatsApp and !threema https://eprint.iacr.org/2017/713.pdf

      TL;DR: Attackers can often rewind members of group to previous state (replay attack), WhatsApp can add arbitrary users and thus circumvent #e2e crypto in all group chats easily.

      BTW: #Threema fixed the issues, WhatsApp ignored, Signal wants to introduce a new protocol in the future.

    Chrome may remove security feature #HPKP in 2018. Just because they can. It is a very robust and powerful technology to protect against very strong attackers,… used by !threema, Posteo and many other companies use it…
