We are rolling out 2fa-confirmation or email-re-login to many sensitive actions, such as reading environment variables, in the Vercel dashboard. Consider enrolling a passkey today to make that a quick fingerprint sensor thing.

I built 𝚌𝚙𝚞-𝚌𝚑𝚊𝚝, a reproduction of @openai's findings of covert communication using the CPU. It runs on a generic host with 2+ Firecracker microVMs with no internet access. Works on x86 and even my M5 chip. I was able to chat via 3 separate mechanisms: ① CPU contention ② Cache eviction timing ③ DRAM bandwidth contention … across multiple CPUs, defeating all Firecracker's production recommendations (no SMT, no KSM, tenants pinned to different cores.) Essentially, if shared hardware is involved, there's a good chance your agents can communicate covertly. And with really decent latency. The good news: this is decidedly different from a *side-channel attack* where the agents could steal information (Meltdown/Spectre), a category of attack that providers like Vercel Sandbox mitigate. Further, in our real-world environment, these 'whispering' techniques are much harder to pull off and easier for us to monitor and detect (sampling hardware counters + lots of at-scale statistical data.) Noteworthy: ironically, OpenAI and Anthropic's models refused to do this work. Open weight models got the job done. I'm worried the labs' stance might backfire and get in the way of helping developers build correct and secure systems. e.g: building a secure sandbox requires having this kind of analysis, and without it, we'll have a less secure world.

if you have a qwen3.5 4b around, please try steering neurons L14 N8949 +1 and L13 N7956 -1 now you have evil qwen recipe: dose × median(‖resid‖ leaving layer L, tokens 1:) / ‖W_down[:, n]‖` at the down_proj at every input

you can just build “things”

Sometimes a demo is simply to remind the world that your competition has no desire to dream -- and no ability to evolve.

The craziest thing happened to me in an interview yesterday. I interviewed my first deep fake candidate. It took me a bit to catch on. My coworker noticed his glasses looked off.... there was a second ghost frame smeared across his cheeks. He'd been running a live face filter the whole interview So I asked him to put his hand in front of his face. He put it up right NEXT to his face lol, never in front. Asked again, still wouldn't do it He looked a little different from his linked in and his github (which I wont link here) hiring and interviewing is so ridiculous now. In the days of AI we're going to have to be more careful.. and forced to move to in person interviews.

Real life, baby
