Kind of insane how much of the front page is about security compromises today.

I think we are about to enter a world where security compromises occur at least an order of magnitude more often due to AI. The fact that AI is sometimes wrong benefits the attacker because they can just automate attacking with agents until they breach a system and the failed attempts don't matter.

Nicholas Carlini has a good talk about the risks on his homepage https://nicholas.carlini.com/ (can't link to the talk directly for some reason)

The corollary is that service access will become increasingly penalized, authenticated, and finicky as the most general first line defense against automated "informed brute force" attackers will be to slow or ban access that looks like them.

If you've got a lot of roving bandits with fancy lockpicks, you're village needs to harden the walls, reduce the number of entry points, identify and document entrants more universally, check under more carriages and inside more trunks for stowaways, etc. And with all that comes delays, imprivacy, accusations, false positives.

The low trust world that we're headed towards isn't going to be nearly as fun.

This is just the beginning, once kimi k3.1 is out with cyber curated dataset post training we will likely see far more advanced attacks.

For now most of these appear to be related to supply chain attacks which can be avoided with basic discipline and using features that browsers had for years: https://developer.mozilla.org/en-US/docs/Web/Security/Defens...

SRI only really works if the 3rd-party script never changes, in which case why is it a third-party script?

If it changes and the hash no longer matches perhaps due customer changing config then the site is faced with the challenge of either the browser refusing to load the script (with potential breakage) or reporting the change which then is probably ignored

It's not really a simple fix for the way the web is built today

usually scripts have versions, this protects you from compromised cdns as well where you publish assets in a different location compared to where your frontend is served.

If a library serves a script and your site manages user funds you should probably avoid using it or use a cdn that does.

I am not quite sure, but there's also other integrity mechanisms that gurantee that a file was signed by the library developer via a served header with the signature of the file.

For 50 years, computer security has largely been built on the theory that most targets aren't worth the relatively high effort to compromise, so it's not worth it to spend the money on security. We're now reaching a point where the effort to compromise is dropping close to 0, which means we've got 50 years of insecure software to reckon for.

The advice today is the same as it has ever been, though. Always assume that any networked computer is or may become compromised. Do not do anything critical on a networked computer, because it is or may become compromised. You can still use computers, but assume that a bad actor may take control at any time, and plan for that eventuality.

For example, if you are hooking up a networked computer to your town's water supply system, ask yourself "what would happen if Iran got complete control of this system?" If you're putting your school system's students' mental health data into a networked computer, ask yourself "what would happen if all of this data became public?"

A better framing is that security has largely been built on theory that most targets aren't worth the effort to target, so security spending is focused on preventing/mitigating untargeted spray-and-pray attacks.

Computer security has largely been built on the “not enough bears” theory.

Every target is worth attacking, but there are not enough bears to eat everybody. Sure, the bears are breeding, but exponential growth does not look threatening until it suddenly is.

How much tax revenue does the UK government get from polymarket. Why should UK tax payers pay to investigate a breach of their systems?

Is it even accessible in the UK?

Friend of mine, who's been treated as the unlucky one as an inside joke, made a binance account - after avoiding crypto for years - just hours before the hack happened, it's now official lore that this whole chain of security incidents is entirely his fault.
