We're open sourcing SPACE, the sandbox platform that runs every task in Perplexity Computer.
SPACE gives each agent task its own Firecracker microVM and controls credentials and outbound traffic from outside the VM.
Available now under Apache 2.0: github.com/perplexityai/SPAC…
I really love reading this. This is in my opinion how security research used to work, and I believe that now it even accelerated. When ever you had an idea you just went after it and you had peers to discuss about those ideas, get feedback, improve them and get them implemented and tested.
That’s why I believe most researchers adopted AI naturally.
Same goes for Andrej Karpathy auto-research, people were amazed about it, I doubt it had the same impact in the security community, that’s what Michal Zalewski @lcamtuf essentially did with afl and what evolution fuzzing was about, among other things in the security community.
Am I wrong?
A retired NASA engineer who had worked on the Space Shuttle program for 25 years was hired by SpaceX at age 62. He described the first week as the most disorienting experience of his professional life.
At NASA, a design change required 3 meetings, 2 committees, a review board, and 6 to 18 months of documentation. At SpaceX, his new supervisor said "if it works, build it. If it doesn't, change it by Friday."
He sat at his desk after the first day and called his wife. He told her he felt like a man who had been swimming with ankle weights for 25 years and someone just cut them off. He could move. He could decide. He could build something in the morning and test it in the afternoon. The constraint that he had accepted as the nature of aerospace engineering turned out to be the nature of bureaucracy.
Within 6 months he had contributed to more design iterations than he had completed in his last 5 years at NASA. Not because he was working harder. Because the time between having an idea and testing the idea collapsed from months to hours. The same brain. The same knowledge. A different operating system.
He described a specific moment where he proposed a modification to a Raptor engine component. At NASA, the proposal would have entered a queue. At SpaceX, the modification was machined by the end of the day and tested by the following morning. He watched his idea become a physical object in 18 hours. At NASA, 18 hours would not have been enough to schedule the first meeting to discuss whether to schedule a meeting.
He told an interviewer: "I didn't get smarter when I went to SpaceX. I got faster. The intelligence was always there. The system was in the way."
The difference between SpaceX and NASA is not talent. NASA has extraordinary talent. The difference is the time between a thought and a test. SpaceX compresses it. NASA elongates it. The same engineer produces 10x more at SpaceX than at NASA because the bottleneck was never the engineer. It was the meetings about the meetings about the work.

That is a *wild* demo...
Today, @washingtonpost covered critical vulnerabilities @depthfirstlabs found in TikTok. These vulnerabilities allowed hackers to access anything on a user’s device that TikTok itself could access, including the camera, microphone, payment information, photos, and the user’s entire TikTok account.

If you are wondering how Grok Bot works on macOS shadown.github.io/blog/posts…
So the problem seems to be that the PoCs are being analyzed as attacks and rejected by the email server…how am I supposed to send security vulnerabilities + PoC exploits?
Replying to @X
@X @elonmusk I'm trying to report some security flaws I've found the only contact I've found was [email protected]. I've got the response that the email account [email protected] doesn't exist anymore or that it is no longer in use. How do I report you guys what I've found in Grok Bot?

Less than 400 lines of nix, that's all it took:
Asked an agent to make @OmarchyLinux on @nixos_org
It went pretty far -- github.com/fzakaria/nix-home…
You can can continue.
It packed: oma-app, tensaku, ttfx, and every other tool, theme and wallpaper.

I believe we are all willing to help. Care to elaborate a bit more in detail? I’ve been designing and implementing a defense system for some time already, I’m sure many people I know are doing the same.
