Why The Government Shouldn't Break WhatsApp

  • Published on: 03 July 2017
  • Encryption backdoors - breaking WhatsApp and iMessage's security to let the government stop Bad Things - sounds like a reasonable idea. Here's why it isn't.

    This is the first video from "The Basics", a series of three pilot computer-science videos I'm putting out in the next couple of months. This one's opinionated; one's explanatory; and one demonstrates coding. It's been a while since I've done this sort of thing -- thanks to the folks who helped proofread my scripts!

    Even if you are not worried about some government doing this, I would be worried about that backdoor enabling also criminals to read the communication. (I guess that depends on the specific type of backdoor, though.)

    Amazing nuanced articulate presentation of the issues... I loved the clarity of this especially the summary at the end. For some, it might be TLDR but honestly, worth it for all to fully comprehend. Thankyou Tom Scott!

    I'm just gonna say it... The government isn't supposed to know everything illegal you do. It's not supposed to know every time you listen to a concert you didn't pay for, or forget to pick up a piece of litter, or drive a bit too fast because you're late for work.The reason we have laws is to constrain the arbitrary rule of government officials - it's a democratic constraint on the executive branch - and NOT to give them power to judge you at every moment in your life. This is a fact that authoritarian personalities want us all to forget.

    Privacy is just apart personal space and having an invasion of personal space be legally allowed is a.. questionable decision.

    What really annoys me is when I sign up to a website or forum, and then I get an email from them, telling me the password I signed up with!

    The government mandates putting a back door in software, then someone will find that back door and exploit it for nefarious reasons

    Came back to see if I could hear the high-pitched noise. I still can, (I'm 11) but it's faint and usually overshadowed by Tom's voice. Plus, I usually watch videos on low volume with captions on, so it's basically indistinguishable. I think some devices may not play high noises as well, because my tablet doesn't play the high noise.

    I can't hear the CRT hiss, but I think it's just because all the electronics in my office generate it too. I think I've finally killed off that frequency for my brain.

    get a warrant for the phone itself, problem solved. want to keep it secret? tap the phone itself (spy program on the phone). they just want to be able to target people without having any checks on who they spy on.

    Since Facebook bought WhatsApp in 2014, this video should have been about a different encrypted message app.I prefer Signal, since it's open source, and can be audited by anyone. While only Facebook knows what WhatsApp is actually doing behind the scenes, and knowing Facebook. Well, they definitely got your nudes.

    Also, everyone has a few things to hide--namely, a certain 16 digit number, a month and year, and the 3 digits on the back

    If someone is cool with government spying bc they “have nothing to hide” they’re 1) putting themselves at risk in the long term and 2) throwing everybody else under the bus

    I am 100% sure WhatsApp has a app or even hardware level back door (within ARM based chips) that has been in use for years.End to end it maybe, but what's the use when the thing on the other end is no doubt plagued with government backdoors.

    I agree.This solution I am suggesting for many years.More police and protection is required not privacy breach.

    How to be secure online:1. Download an open source PGP program (duckduckgo will help you)2. Generate a PASSWORD PROTECTED key pair, and send the public key to all your friends (your PGP program will have an option to "Send public key by email").3.Collect the public keys of your friends, your PGP software will save them in a contacts list4. Write any message you want to encrypt in a textile, encrypt with the recipient's key, copy and paste encrypted message to email, WhatsApp etc and don't save the .txt file (or secure delete it)If all that seems like too much trouble, you probably don't really care that much about security....

    welp you lost me on this video. Sorry their is a MAJOR difference between a wire tap (a warrant necessary action that allows the law to "listen in" on a conversation) and a back door (an INTENTIONAL hole in software that can be found by anyone that allows them to bypass normal security). I hate the statement "I have nothing to hide". Specifically because it has NOTHING to do with whether or not a government should be able to spy on me or not. Talk about an argument based on no facts.

    You don't have to break encryption to read the messages... you're typing into an app. No magical encryption backdoor, just an app UI security flaw or maybe an app UI backdoor

    I absolutely promise you, if they create a back door, it will be hacked before the next DEFCON event. Clipper chip is the best example because it was everything they ever wanted, /and/ it was immediately compromised.And ... now they're requiring people to be searchable at US customs, and our NSA was tapping the German leadership ... How's that for a 2 years later look back?

    I still suspect this is why Brexit was pitched to the peasants. EU law puts a big dampener on that.
