      Unfortunately, i am pretty sure BrainFlayer will work for #bitfi soon. My friendly recommendation for the @Bitfi6 twitter account: Get an engineer on board & stop making elite security researchers angry with toxic replies. The feedback might be vrry uncomfortable. For you.https://twitter.com/TheBitfi/status/1023512866245279745 …

      That BrainFlayer tool is very primitive and won’t work on any properly set up Bitfi wallets. But good luck with it.

      Hi Florian, it will not work. First, BrainFlayer works on only extremely primitive phrases. Second, we have update coming out that would render BrainFlayer completely useless. Not a single customer will be affected by it.

      Unfortunately, people tend to use "extremely primitive phrases". From my understanding it will work, but ofc it's perfectly possible you start a hide and seek game which will ultimately initiate another reversing challenge hackers will happily accept. Ryan is obviously the expert

      Hi Florian, if our customers follow instructions to select just 7 words for their phrase (which doesn't include salt) how on earth will BrainFlayer crack it? Please see this: https://theintercept.com/2015/03/26/passphrases-can-memorize-attackers-cant-guess/ … After reading Ryan's article we do not consider him an expert.

      You are free to consider him what you want. The rest of the industry has a different view though :D

      Replying to @Marsmensch @Bitfi6

      Not reasonable to claim Bitfi is secure because they tell people to use diceware - that's like stating the pull-out method works well for birth control. You have to account for what actual humans are going to do. This is why safety interlocks are required on dangerous machines.

      Replying to @ryancdotorg @Marsmensch

      Hi Ryan, the person who was handling this Twitter account has now been dismissed because of many cocky & insulting remarks to smart researchers that we have a lot to learn from. Would it be ok if we contact you? We could use some help to address any potential weaknesses.

      Loading seems to be taking a while.
