I'm not sure I follow. A brute force attack generates a key which can then be tested against the target. This isn't magic, in fact, the more detailed answer above made the same argument essentially. Thought they provide a different argument suggesting that it may be possible to increase the ability to guess keys correctly.
I would think that if the rate of guesses is only one per second it would take eons to find the correct one. I was just wondering if there is an offline method. Just wondering how safe we can be when the news comes out.
I assume you are correct. I also assume you and I are somewhat safe. You have to consider the likely hood of an individual getting a hold of one of these devices in the near future. Then again you really have to ask if there is any reason you in particular will be targeted by someone with this technology.
Eventually everyone will be targeted. I have an unannounced web server serving a domain in the middle of internet nowhere and I get script attacks all the time. If some how this gets commercialized with no regulation criminals will open up shop for business practically the day after. Its like CRISPR: sure it can do some powerful things but so can your adversaries to you. I hate to think of the internet as a cloud of adversaries but that is really what it has become.
CRISPR fears are really overrated. It is nowhere near as mature as it needs to be. Further, you're less likely to make anything useful with it and more likely to just kill the organism you are trying to create. I work in a biotech lab, and we hardly ever use it and instead opt for manual plasmid knock in/down or tissue engineering techniques instead. The extent of work you have to put in to actually get something useful from CRISPER is prohibitive of it being used to target you and I.
