I really don't understand why people decide to work in computer security, today it's really an arms race. I see how it's like games of lockpicking, but honestly I don't understand the value of it. It's like being in the arms trade: what matters is who you decide to trade with. Honestly, I'd rather see myself as anti-cyber-war at this point, like anti-war protests, meaning telling people to use computers for less crit…

> telling people to use computers for less critical tasks, and disengaging from certain areas. I think I a bit can understand how you think. Looking at some health care related apps, I was surprised to see how buggy they were (the user interface) and silly built, wrt security. On the other hand, without computers, the alternative seems to be that the health care staff picks up the phone and just assumes you are the o…

Which ones may I ask? I’ve been shocked to learn how many online EHR/EMRs work... it’s a bit frightening to think it would be trivial to find large densities of ailments / preconditions to exploit at a state level.

Hackers ARE using zerodays to infect EVERYTHING. I really can't understand why people continue to just assume that their endpoints and networks are clean. Worse, they then use the lack of security events to justify not buying the tools and expertise that are necessary to identify compromises. EDIT: not just zerodays. Many organizations have patch schedules that are too slow.

I think the average person doesn't know how to prevent it and believes that learning out would be beyond their abilities.

How long until we realize that JIT was a mistake and that we should offer orders of magnitude slower JS in browsers that is actually safe (or start building webpages without JS at all again, which will probably never happen) lest we give every website the ability to take over our device? I'd pay real money for a browser with a slow, safe JS interpreter.

why do you assume an interpreter is any safer than JIT? kinda like saying arrays are better than matrices.

Timing attacks are easier with a JIT e.g. I have seen eBPF referred to as a spectre-accelerator

Processes were a form of robust virtualisation once. It’s just pushing the problem down another layer. There are vulnerabilities in virtualisation layers too.

> Processes were .. Was it ever robust? Or just that there weren't yet so many exploits?

It’s a good question. Perhaps the same is true now with virtualisation.

But these are attacks that worked across multiple systems. Heterogeneity is going to lead to more systems with less overall security work being done per system. Sure, using Firefox would have prevented the attacks we know about, but who's to say Google found all of the attacks. They exploit Chrome, Samsung browser, Windows, Android, iOS, and Safari. It seems silly to say "if we had one more, it would have stopped the…

> They exploit Chrome, Samsung browser, Windows, Android, iOS, and Safari. It seems silly to say "if we had one more, it would have stopped them." Samsung's browser and Chrome share 100% of attack surface; Safari and Chrome share likely near 70%. Windows and Android have Chrome built-in at the OS layer, iOS has Safari built in at the OS layer. In this case, something like Firefox which shares much less attack surface…

>Windows and Android have Chrome built-in at the OS layer

How is Chrome built into Windows at the OS layer? Wouldn't that be IE or Edge?

Edge is now Chromium based and soon Edge-Chromium webviews will ship with the OS. The old IE/Edge webviews will remain for legacy but they'll eventually get stripped.

The only thing that comes to mind is having most websites be sites and not apps . Most sites don't need custom fonts, JavaScript, and CSS. If Firefox & Chrome had support for something lightweight like Gemini ( https://gemini.circumlunar.space/ ) then most sites could just use that. With that sort of setup, restrictions on the web like uMatrix would be a lot less painful because most sites wouldn't ever need to be wh…

I agree, and on my computer I disable custom fonts in the web browser anyways. A better web browser is really needed; one of things it can have is support for the Gemini protocol and file format. (It can also omit many things, as well as adding things.)

What else to omit? Not snark. I'm playing with a Firefox fork and ripping stuff out (pocket).

I think that's OP's point. Edge uses chromium.
