How people react to php shows their skill and my conclusion is I will continue believing only top CTF players who has been before the AI era

if this PHP vulnerability allows remote code execution, doesn't that mean we can use the vulnerability to auto-patch all vulnerable servers?

Last night, a swarm of Opus 5.5 agents working for 9 hours and burning 254.2 million output tokens were able to fully reverse engineer and decompile the Linux source code Full source archive available here kernel.org Grab it before they take it down

Mistral is a beast! 🔥
🤖 Made with AI
Meet Mistral Large 4, aka Le Chonk. • 1T parameters, natively multimodal. 49B active. It is the best open weights model from US or Europe on aggregated benchmarks. • State-of-the-art on critical workloads, including cyber defense, manufacturing and finance and it surpasses closed frontier models on visual grounding. • Forged in Europe end-to-end and is deployable from Europe via our own Mistral Cloud infrastructure. • Available to all via API today. Working with cybersecurity partners privately. Open weights release end of October.

I think it's wild that AI has turned software developers into QA testers.

Update your MikroTik RouterOS again, to at least 7.24.3 Just published a blog on how you could turn the Webfig "file-read" CVE-2026-67281 (already published by @CERT_Polska_en) into a delayed RCE and on *two other RCEs* in DHCP relay and Webfig. More: sijisu.eu/posts/3-mikrotik-p…

For researchers that want to know how this is done without going on AI-heavy details: ( affordable DIY at the bottom ) They took a model, and compressed it to be able to run on a single 4-GPU (still expensive for non-enterprise, so not for solo use - think $80/hour or $180,000 purchase). Their process / methodology: - Pick a model with the expert architecture - Choose a calibration dataset that matches the intended use ( So audited codebases v.s. reports etc) - Run the calibration data through the unmodified model and record two numbers per expert per token - Compute a single score per expert - Delete the lowest-scoring experts in each layer The expert's weights are dropped from the model file, and the router's output columns for those experts are removed so it can only choose among survivors. The router then renormalizes its weights over the remaining experts as it normally would. This is EXPENSIVE. BUT it's no different than the token game you play v.s. large scale security companies either way so no reason to give up. You can do the exact same process for a smaller model and have something you can run on your mac or a hetzner node. 🙂‍↔️🙂‍↔️ Affordable DIY plan: 1. Start from the unpruned GLM-4.7-Flash 2. Collect a few hundred to a thousand traces from your own audits 3. Run the Cerebras REAP repo over them on a rented A100 for an hour or two. Under $10 of compute. 4. Prune 25%~50%, quantize to GGUF, load in LM Studio or whatever. 5. Run locally on your mac

i thought read() was a syscall wrapper, but it can dlopen a bytecode interpreter and execute your code "house of windy" turns this into leakless code execution with only OOB null byte writes pepsipu.com/blog/2026-09-dwa…

Mythos audit is also from May 2026. It’s like 20 dog years in AI time. You could probably rewrite curl in one shot in rust today with Astra

🚨GPT 6 Astra benchmarks are absolutely ridiculous • ARC AGI 3: 98.6% • ExploitBench: 100% • SRE Bench: 99.2% • AutomationBench: 41.4% What the hell did OpenAI cook up here ??
