    The third has been systems that telecommunications companies use in compliance with the Communications Assistance for Law Enforcement Act (CALEA), which allows law enforcement and intelligence agencies with court orders to track people’s communications. CALEA systems can include classified court orders from the Foreign Intelligence Surveillance Court, which processes some U.S. intelligence court orders.

    These are the same groups that want back doors in encrypted apps so they can read our communications catch criminals. And yet, look what happens when they have access to that information.

    I absolutely encourage people to use encrypted apps all the time, even when there isn't an attack campaign we're hearing about.

    I know they have to say that, but I can’t help imagining them trying to keep a straight face while doing so.

    “China firmly opposes and combats all kinds of cyber attacks.”

    From the article:

    From the article:

    In the call Tuesday, two officials — a senior FBI official who asked not to be named and Jeff Greene, executive assistant director for cybersecurity at the Cybersecurity and Infrastructure Security Agency — both recommended using encrypted messaging apps to Americans who want to minimize the chances of China’s intercepting their communications.

    “Our suggestion, what we have told folks internally, is not new here: Encryption is your friend, whether it’s on text messaging or if you have the capacity to use encrypted voice communication. Even if the adversary is able to intercept the data, if it is encrypted, it will make it impossible,” Greene said.

    The FBI official said, “People looking to further protect their mobile device communications would benefit from considering using a cellphone that automatically receives timely operating system updates, responsibly managed encryption and phishing resistant” multi-factor authentication for email, social media and collaboration tool accounts.

    The scope of the telecom compromise is so significant, Greene said, that it was “impossible” for the agencies “to predict a time frame on when we’ll have full eviction.”

      • Exemplary

      Short answer, there's not a ton we can do to mitigate this as individuals.

      I think Signal is a reasonable choice for end-to-end encryption of text/video/calls.
      Use of things like signal in a business or government environment is hampered by data retention requirements.

      We should always keep the limitations of E2EE in mind. As always, when speaking of security matters, it's good to have a threat model in mind.

      E2EE of your messages might help keep you from getting caught up in a dragnet data harvest hack. The attack described in the article is fairly broad in scope, but still targeted in specific ways, so something like signal would probably help.

      However, using E2EE doesn't matter that much if someone (especially someone with nation state capabilities) wants your specific data. The data is still present and vulnerable on the individual devices, so they would likely choose other, targeted attacks to access that data after it has been decrypted.

      That's just messaging. Our lives are tied up in online banking, insurance, and medical apps that we have no choice but to use. I know someone will say there are some choices, but I believe they are meaningless in practice. The bar for security is low across the board, and most organization's security practices are opaque – that is, even if you had the time and expertise to audit five banks security practices before choosing in, you wouldn't be allowed to. So in practice those choices are uninformed.

      Caveat: I'm speaking from a US perspective here. I gather things are better in the EU due to better regulation, but I'm not sure how much better.

        I gather things are better in the EU due to better regulation, but I'm not sure how much better.

        Only in theory. In practice, everyone (state, companies and consumers) uses all kinds of IT products from the US. There are efforts to mitigate this, but that would cost money and political effort, and there's always something more important than changing a somewhat working system.

        I think the issues are very similar across the world, and they basically come down to this: With physical products, they feel bad if they are creaking, leaking, gunky, etc, even as a complete layman. An IT product can have all kinds of severe issues and still feel fancy and polished. And then there are things like social media or mass surveillance, for which we haven't really understood the large scale consequences they can have on societies, even if they were impeccably implemented.

          I’ve read that the US is worse due to starting out with lots of smaller phone companies and lots of mergers. It would make sense to move to not trusting telecom with anything other than encrypted traffic, so then insecure hardware wouldn’t matter much. (And this is what the web has been migrating towards since the Snowden revelations, so it’s well along there.)

        @chocobean, a few other things I thought of:


        Prefer 2FA apps over SMS/Email as a second factor when available. That way, hacking your email/sim card doesn't gain the attacker access to the second factor.

        I have been using Authy for a while. I think their practices are not stellar, but I haven't had time to research alternatives. One thing they do is keep an encrypted backup of the secrets, which is nice if you lose your device or the data on it.

        Caveat: many services will let you reset your password and 2fa credentials from email, so it may not be as much more protection as it seems. But it is still easy to implement and adds a layer to the attack.


        If you need to send credentials to someone, instead of sending them the password by email/text/whatever, use onetimesecret.com to create a single use link. When they click on it, they will get the secret, and then the link will be dead after that, so nothing sensitive hangs around in logs of your email or messaging app.

        It feels hinky to put your password or other credential into a random site. They claim they don't access them, but there are no technical limitations in place to enforce that.
        The reason I consider it better is that that password is shared out of context, so if you are not reusing passwords, even a leak there doesn't leak much.

        If it bothers you a lot, the tool is open source and you can run your own copy.

              At least pertaining to the official apps (the protocol itself obviously can't enforce it), the disappearing messages setting is bidirectionally communicated/changed in Signal chats unless you use a fork to circumvent this. The changed setting also only applies to messages going forward, so you can't retroactively decide to retain a message sent in ephemeral mode.

      Signal, iMessage, and I believe WhatsApp are all end-to-end encrypted by default.

      Signal is the only one run by a nonprofit and is easily the safest widely available option, even if its feature set is a little barebones.

      I think Apple is pretty trustworthy in this regard (their business model is not built on data collection), but iMessage only works on Apple devices so it's a non-starter for talking to anyone outside that ecosystem.

      WhatsApp is owned by Facebook. I don't trust them.

      Stay the hell away from Telegram. Chats are not encrypted by default. Encrypted chats are tied to a single device. Group chats cannot be encrypted at all. They also have ties to the Kremlin. The fact that they advertise themselves as a secure messaging platform is downright laughable.

            • Not everyone has a good password management system and offering native logins during sign-up really through them off when later they were presented with social logins (this might've been fixed now)
            • They have issues with notifications not appearing correctly on IOS and I don't have any advice for them.

            That alone is a much worse experience than the competing platforms.

As far as the native login vs social login, i feel that's not just matrix clients, but many areas of digital life nowadays, where as a tech-literate person i can see through the fluff, but were i to be less tech literate, i would find the world vastly more annoying to navigate...and then resort to fallbacks like poor password management, etc. - and of course can't really blame the normies, since tech is harder than it really needs to be.

              Ah, and to the point of notificatins not apperearing for IOS, unfortunately, i have zero advise there because have never used ios device with matrix clients (except for one brief weekend for my offpsirng)...however, i wonder if that has to do with IOS' issues constantly killing background processes and silently suppressing said notificaitons due to that proc. shutdown? If so, i wonder now how other chat clients handle that? Sorry, not giving any answers here.

      How well does your government do online services as it is? I'm curious because if the USA made such apps it'd results in terrible apps that barely work with a user interface that looks like it was designed by the programmers as an afterthought and it'd cost hundreds of millions, if not billions to create. That's not even getting into how it'd be subverted for political party propaganda and spying.

      It's almost a joke how our grossly overfunded federal government has such crappy web services. Makes me worried our leaders are not taking the internet and new tech seriously. Until recently (at least for businesses), to do anything we've had to call or write to the IRS with no website to do things like find out why they think a payment is late or we owe some weird amount (usually due to misapplied payments). This is just sad for one of the supposedly most advance countries, we ought to be rolling in new tech, but we're run by the technologically challenged and technophobes. 😭

      We even struggle just to get the government to help file returns (just got a website for that and it's not even fully functional) which could even be automated by now but we're still stuck on phones and paper. They're citing concerns over job loss (not an excuse to bar progress imo) and cost (a few hundred million - my STATE brushed that much off when a past governor flubbed an attempt to make an insurance website and a single fighter jet can cost over $100 million and they plan to purchase 60 next year).

        [other Canadians please feel free to jump in / correct. For the purposes of this post I'm not making a difference between browser apps and phone apps]

        Availability for online provincial (eg State) government services will depend on whether your province has money (Ontario/BC) or not (Atlantic provinces). Eg I just tried to renew a health card since May, and it's taken me two attempts to fax, two attempts to physical mail, and finally calling them once again to be finally given an email address to do it. So something digital would be great. Not all bad, though: their energy efficiency program was registered online and pain free. They pay for a licensed electrician to come install one each motion sensor light outside and inside, two dimmer switches, smart thermostat per level, one of those under the door air things, door foam things, buncha freebie LED bulbs and other small do it yourself things. For healthcare, my poor province and the rich ones are all using a private virtual doctor app : smooth easy mostly free access and I hope secure. Oh and elderly grants and rebate things are strangely online: Ive been helping a neighbor fill in her things. I'm pessimistically choosing to see this as a ridiculous hurdle rather than a convenience though. In BC, I'm a big fan of the crown car insurance / driver license bureau - most things done/pre-booked online and sleek and efficient. Dad had to renew license and walked out of the appointment in less than 10 minutes.

        Nationally we also had a scandal last year where the provincially partnered (eg no consumer choice) medical lab company had a data breach and hackers got all our health records yay, and we got settlement money of $50-150 dollars.

        Nationally it isn't too bad: student loans online were fairly straightforward online 20ish years ago. Many other things like unemployment insurance, parental leave benefits, tax return info, pretty painless online. Passports, you can check the renewal status online, and book an appointment to do it in person online as well. The national job search / ads database looks and feels web 1.0 but secretly I'm a fan of old web UI.

        I'm sure I'm forgetting a bunch of government things to do online that I've taken for granted. The health card renewal was so surprisingly painful I had forgotten most things could be difficult.

        Oh yes! A bunch of interactive maps! . I perpetually have a few bookmarked for [not exclusive list] which beaches are open/closed for shell fish foraging; which pieces of crown land might be open for tree cutting and to submit citizen request for questions; other geology and geographical things like forest density and species / water flow and drainage/ elevation /karst risk / radon risk / 10k satellite / property boundary / bedrock formation etc. The shellfish one is actually maintained and updated pretty frequently, I'm very happy about it.

        Most municipal zoning maps are online as well, but some are still awful pdf era. The richer municipalities do tax sales and recreational program registrations online. Libraries are all basically online as well what else....

      For this particular threat model where the goal is to not let the Chinese hackers who are in US phone systems see your messages and maybe listen to your phone calls, nearly all websites use encrypted connections nowadays and that is good enough.

      Email is complicated; not all email is encrypted in transit, but it often it is if both sides support TLS.

      Similarly for chat messages. Messages sent between Apple users and between Google Messages users are encrypted. SMS isn’t encrypted and a likely vulnerability, but can often be avoided.

      It seems like the easiest thing to do (if both sides agree) is to pick the same chat app where you know it’s encrypted. I’d trust Signal the most. Others would probably work fine, but it might be easier to slip up.

      It seems like the hard thing would be to get out of the habit of using the phone; instead of just talking, you need to agree on a different way to talk, which is hard when the other end is a business. For non-businesses, people can probably switch to some other chat.

      I wonder what US politicians will switch to?
