“Aperture Science: We do what we must, because we can.”

EDIT: Also: “Science isn’t about why - it’s about why not. Why is so much of our science dangerous? Why not marry safe science if you love it so much? In fact, why not invent a special safety door that won’t hit you in the butt on the way out, because you are fired!”

Yes, this is it. I bought it because it was cheap (100€) and had a built-in CPU. The only problems are that it hasn’t got many SATA or PCIe ports. This is fine however, because I have no need for them right now.

You just changed half my life.

This is a custom built mini PC, with a mini-ITX motherboard and an Intel N100 CPU. It gets powered by a power supply that I got from an old computer. Also, it needs no active cooling, just a heatsink. It almost never gets above 60°C.

(and yes, it has no case).

In it I run:

• Jellyfin
• All of the *arr stack
• Pairdrop
• My website
• My personal Lemmy instance
• Immich
• Pi-Hole
• Home Assistant
• Grafana/Prometheus/Node-Exporter stack for monitoring

Is it just me, or have I seen like 6-7 of these posts at this point?

Oh, I missed the L1 in the title. Basically, all the decryption at L1 is happening inside a Trusted Execution Environment. This is a dedicated chip that does all encryption-decryption (among other things). This is why it is so difficult to extract the keys, because they don’t enter the CPU or are stored in RAM, because the dedicated chip handles all of these.

So I don’t think you can find a guide about this, because if anyone has found even one exploit, they would be keeping it to ourselves, so that it doesn’t get patched.

Although it is very difficult, I think the only real solution is to reverse engineer a TEE and find an exploit yourself.

If you manage to do this, please let me know! I am happy to get updates about progress in this topic.

I have heard about a TamperMonkey userscript called EMELogger that logs some information about EME, in the web tools console making it easier to get the PSSH. I haven’t tried it though.

Also, I don’t think you will find guides on paid content as this is considered highly illegal (I think).
