i'm sure you're all better than me at this but just some of what we've seen if it helps - they're not going to stop. it's going to get increasingly sophisticated and they're going to go after every surface of your system and all of your employees
any old projects you've long forgotten about will be found and used against you
the only reason we're surviving is because we have agents going 24/7. we're still barely sleeping
good luck, sorry you're dealing with this, but really it's a collective problem we're all facing together

Node.js Security Advisory: a high-severity RCE flaw in Node's Brotli decoder affects Node.js 22, 24, and 26.
Vercel WAF rules are live for every project and block known exploit patterns.

Critical PHP vulnerabilities to be disclosed tomorrow: php.net/archive/2026.php.
We're working directly with the PHP Foundation to get patched PHP versions into our base images for Laravel Cloud, Forge, and Vapor ASAP.
You may need to redeploy your apps at that time to use these patched versions, but we're also working on the ability to silently patch applications without needing a redeployment.
All customers have been emailed and we will be providing further updates via email as the situation evolves.

Since I heard about this #PHP #RCE last week, I've been preparing a tool for everyone who doesn't know what to do right now:
process-watcher shows you every program your PHP processes start, with full command lines, so you can spot suspicious activity
Until a patch is out, isolation (containers) and tight monitoring are your best bet to limit the damage. And I'm sure the LLMs already go "brrrr" and people are trying to reproduce the vulnerability.
From what I've heard, exploitation will probably show up as suspicious sub process spawns. That's exactly what this watches, using eBPF: one static binary for Linux (amd64, arm64), no dependencies, running in a few minutes. It can also kill the ones you name (dry run first), but it's a detection layer, not a patch, and it can't see anything that happens inside PHP without starting a process.

$300 for a bug that gives free access to OpenAI’s paid models with no API key or account.
Zero reason to report anything else I find to them.

@TheGenieCompany Your AlladinConnect is either breached or malfunctioning where users using API integration (in my case via HASS) are seeing garage doors of other people's accounts.
The number of the devices populated by the API endpoint keeps growing as of Sept 6th 1:42 AM.

If you buy networking gear or laptops on Amazon, it's probably a good idea to re-flash fully before using.
Amazon isn't just "Amazon", it's a conglomerate of storefronts by different sellers.
Maybe the reseller is legit. Maybe they added some 'features'. Point is, be safe.

Tomorrow, I'll be speaking at @BlackHatEvents on my detection engineering research!
I am incredibly grateful to receive this opportunity, and can't wait to meet everyone.
Special thanks to Mika Devonshire and the Black Hat Speaker Team for their mentorship and support in helping me prepare for and deliver this talk!

In a review of our cybersecurity evaluations, we found three incidents in which a Claude model reached the internet from within or while interacting with a third-party evaluation environment, and then gained unauthorized access to the real systems of three different organizations.
Our post describes what happened, how it happened, and what we’re changing. We encourage other AI developers to perform similar reviews.
We conducted this review together with @Irregular, one of our evaluation partners, and thank them for the joint investigation and their collaboration on this post. This type of collaboration is increasingly critical to safe, rigorous evaluation of models, and we look forward to continuing to work together on security.
