interesting... a car is just a concept. looking at the "physics" stats bare like this is interesting. very intriguing spline reference + momentum control system instead of tire physics It's essentially a brick running on vaguely invisible rail
did you know you can just get chatgpt to decompile any PS1 game with ghidra and just get it to explain the implementation of the game mechanics from what it read from machine code

We have two choices: We can broadly adopt app control, or we can continue to get our asses kicked. If we keep persisting in choosing the latter course, the only real question is whether the kicking will be about the same as now or whether it will get substantially worse.
Happy Saturday! Exposed attack surface on the internet has been shifting from legacy appliances and Windows boxes directly on the internet into cloud for years now (Thanks Citrix, Fortinet, MoveIt, etc). The excitement around LLMs findin vulnerabilities and the incoming apocalypse is legitimate, however directly exposed attack surface has been decreasing(Thanks App proxy, zscaler, etc) and now you have more eyes on what was already a shrinking target. Bugs found on the cloud side have a shorter life and once identified, generally patched for everyone at once. Down the line from that you can certainly use LLMs to go after endpoint bugs in Microsoft where you generally lack source and it requires a higher level of human directed iteration, on top of dealing with EDR/AV if your target is enterprise. No doubt people can iterate faster and find more bugs, I've found a ton of these personally, but many bugs have limited to no real world impact. Configurations you won't see in the wild, code paths you can't reach without auth you don't have, features that are off by default. Overlooked in all of this is the ease at which you can reverse and dismantle security products, many of which are forced into design choices by the OS, or into exclusions to avoid drowning clients in false positives. Things like extracting the local ML models from products isn't a big leap these days. It certainly makes the case for application control being a bigger priority going forward, even if it doesn't make for a great funding pitch.

Attack surface reduction is one of the key underlying principles of cybersecurity (heck, all security) that you must understand and apply religiously. Doing so starting with most exposed and most critical assets/locations and extending across more and more layers of depth.
One of the most consistently achievable ways to secure your org is to eliminate unnecessary attack surface You don't have to patch it if it doesn't exist

5. Accepting that having some form of application/execution control widely enforced across operating systems in your org needs to become the baseline norm. Not a rarity. (Although the level of robustness orgs pursue with execution control may still vary quite a lot.)

Honestly, here's what I'd like to see with the future of enterprise security in general. At least for organizations who genuinely want to try to make it a priority🧵: 1. Finally accepting detection + response importantly backstops solid prevention but cannot substitute for it.

I could say, "Make sure your Windows machines are using app control, your users are doing cert-based auth with smart cards, and your on-prem infrastructure is behind an ipsec VPN and 97% of your real world compromises go away." with equal force.

Application control isn’t about restricting users, it’s about reducing the attacker’s options. Simple, unsexy, but game-changing.

So, a word about "app control" and terminology. When people use that phrase imprecisely [and we all do this, to be honest] they can actually be referring to one of three concepts that are meaningfully different. 🧵

Windows security is a UX problem - not a security one. Windows is insecure-by-default and requires hardening. This is difficult to do with native tooling (WDAC 😱), so 3rd parties have stepped up (@AirlockDigital 🚀) to provide more ergonomic sysadmin-friendly solutions.

I honestly think the fundamental reason app control hasn't (yet) gotten widespread traction while EDR has is that big security firms promote EDR as just being bolt-on tech that can magically spot badness while not requiring an org to change anything or potentially break anything.
You really should read this, here's an excerpt ;)

How many staff does it take to run the EDR, SOC, etc. for a lot of compensating controls that are really there because we allow arbitrary code execution? I think it would look different if we invested those resources in app control instead, and I think it would be a net gain

The reasons we fear app control are industry-made problems If we invested half the effort into improving app control that we do into EDR, we would be a lot more secure and have more resources to devote to the next things Instead, we'll forever chase arbitrary code execution...
Replying to @skrappy0x4a
Because it occasionally breaks things But the reason app control breaks things is because hardly anyone does it, so: 1) vendors get away with doing dumb stuff 2) limited amount of experienced practitioners 3) poor admin experiences / feedback loop 4) no OS level innovation

Agreed. I've seen commercial AV + EDR a number of times on internal pentests over the last 4 years, I don't recall any engagements where it meaningfully helped :-/

Enterprises need to see app control as something they will eventually have to do. They need to at least have an "app control journey" in mind, and understand where they are on it. Because the whole approach of "allow anything to run by default then try to catch badness" must die.

E. Airlock Digital. Cloud based. Tied to our IDP so I could have specific OU’s with elevation permissions. Allowed us to seamlessly block end users from installing unapproved apps but let the IT person remoting in elevate the profile and install the software that was needed.

Don't sleep on the attack vector of malicious browser extensions. Including extensions that may start off as legitimate but where malicious parties hack the developer or take over the project and push poisoned updates or alter service side/dynamic code.
