Is Matthew Green some industry security personality that people respect? I appreciate this write up, it's interesting. But it seems motivated by his little Twitter rant the other day. Who is he beyond some Twitizen in a Guy Fawkes mask who hates HN? I don't particularly like his demeanor, at least from his rather naively uninformed tantrum the other day. Didn't seem very professional or respectable so I just wrote him off.

  So it turns out APPLE did something I didn't know about.

    My iPhone doesn't turn off anymore when I power it off if I select the option that says "go into low power mode so that my phone can still send beacons". Can you BELIEVE this?
    - dcow 5y ago
      FURTHER, unlike Google who would never let you turn this feature off, Apple does, but I have to GO INTO SETTINGS to find it OMG. And what a jokeshow marketing team Apple has because the name is a little confusing.

        Somehow those bumbling buffoons over on HN found my tweet and half of them LIKE this feature. WTF! They're even discussing this thread like they like to do.

        You're gonna get yourself rate limited. It's no fun.

        You mean "a little bird told you I was going to get rate limited", don't worry I gotchu.
        Jtsummers 5y ago
        No, HN will rate limit you if you post too quickly. I've been hit with it when I was involved in a back-and-forth in the past (part of the reason I added a 2-minute delay to my posts becoming visible, plus it gives me a chance to reconsider if they're worth posting or make edits).
        dcow 5y ago
        I know. I was just being deliberately annoying. Matthew Green's twitter thread includes an incorrect (but he has now walked it back since he's obviously now read the teardown we're supposed to be discussing here and which I've played my fair share in derailing) post about how "a little bird told him it works this way". Just more twitter bravado at the time.

        Huh? How is that 'bravado'?

        Thanks. Genuinely gave me a laugh. I predict HN mods won't be so humorous about it though.
        dcow 5y ago
        I have net lost some karma. Probably should have put it all in one post but I don't think it would have had the same effect. It so clearly is silly and unwanted when you do something like that on this forum, and that was the point.

Matthew Green wrote zerocash, the protocol behind zcash, and he teaches cryptography at John Hopkins. When it comes to cryptography he knows enough to have opinions. It's hard to opine about black box systems, which is why open-source is so important. It's hard to trust what you can't verify.
- dcow 5y ago
  I don't disagree but like if you want an open system why are you using an iPhone? Maybe Green is a little guilty of slurping up Apple's privacy marketing?...

    Everyone is quite an absolute word. How are non apple users slurping up Apple's privacy marketing?

    You can read more of his iPhone-related writing here: https://blog.cryptographyengineering.com/category/apple/ https://blog.cryptographyengineering.com/category/apple/ I'm not sure how concerned he is that it's closed source, I think in this case he was just surprised that the implementation details and security considerations weren't documented anywhere: https://twitter.com/matthew_d_green/status/1443382207838621703 https://twitter.com/matthew_d_green/status/14433822078386217... Note that he was relatively positive about this feature when it came out two years ago: https://blog.cryptographyengineering.com/2019/06/05/how-does-apple-privately-find-your-offline-devices/ https://blog.cryptographyengineering.com/2019/06/05/how-does.... It seems like the motivation for this tweet was "wow I do a lot of iPhone security research and I didn't know this worked when the phone is off, I'm surprised Apple doesn't document the details of this anywhere." Remember that it's hard to interpret tone through the internet, and as someone that doesn't get a ton of engagement on Twitter, he probably doesn't feel like he's writing for a mass audience.

"who hates HN" This site, and this community, is great in my opinion. But it's not without valid criticism, especially considering the impact it can and has made in the industry and tech society. "naively uninformed tantrum" I'm unable to find the posts you're talking about.
- dcow 5y ago
  Sorry if my distaste for these "I'm so cool look at me go" Twitter rants is seeping out here. If you go to his profile and scroll back a few days of posts you'll find them. Anyway it looks like he's humbled and corrected himself after seeing this writeup. Maybe I'll give him another chance.

    > scroll back a few days I did and I'm not sure what I'm looking for. Could you do it and post here so that I can verify what you're talking about?

Matthew Green is a well known Cryptography professional and has a ton of write ups on his also well known blog. https://blog.cryptographyengineering.com/ https://blog.cryptographyengineering.com/ You seem a little judgemental and obviously unaware.
- dcow 5y ago
  Because he posted a bunch of admittedly pretty annoying Tweets based on angsty presumptions about stuff that someone who put in the effort to do their research and submit a real teardown and writeup rips apart. Being some crypto associate professor doesn't absolve you of the responsibility of doing your research before spewing off on Twitter. At least he's seemed to handle things with some amount of humility since then so I'll chalk this one up to having a bad day or something. I've actually read some of his stuff before I just didn't know him by name which is why I asked.
