The drive wasn’t encrypted, a not-encrypted database dump was on the laptop when the raid happened. It might have had to do with gearing up for the Mastodon update that caused us a lot of grief across Fedi a couple of weeks back. Or it could have been database server debugging; the timing was incredibly bad.
But if the drive wasn’t encrypted, how is it “would be encrypted material”?
I’m surprised that people are hosting Mastodon servers without full disk encryption given the overhead isn’t significant plus the fact that people have private messages in the DB.
Just FYI, when your drive is encrypted, and the system is up and running, the keys for the encryption are in memory and thus recoverable. And even if they were magically protected by something like SGX or a some secure enclave, you can still interact with the machine and the filesystem while it is running.
So full disk encryption is NOT a silver bullet to data protection when being raided.
Right, and then these comments about “encrypted database” the server application needs to be able to access that data, so it will have the key in its config somewhere right?
Additionally, hardware-based solutions for attackers have been known for about fifteen years now. Wiebetech, for example, sells a nifty gadget that you plug into a UPS and then carefully slide over the power connector of a running machine. Then you pull the plug from the wall and the machine stays powered up. Net result: Contents of RAM are intact, encrypted drives are still accessible because the OS is still up.
Yeah I didn’t realise they’d capture the memory. I though they just unplug the server and take it.
You could potentially have something that recognizes that the server is being tampered with and automatically shuts it down.
AFAIK it’s not that easy to access data on the machine while it’s running unless they can bypass the lock screen. People pick stupid passwords for their user accounts so it’s totally possible to get in in those cases, but otherwise dont you need really sophisticated side channel attacks to get data out of memory on locked system? It’s not like there is some port on the MOBO you can just plug into to get access to RAM
The DB itself is encrypted (usually).
And FDE wouldn’t have helped if the disk was currently mounted and the admin logged in; LEO attempts to preserve things as they are, they don’t just unplug the hardware and walk away with it.

Which DBs support encryption? Genuinely curious, since I usually use full-disk encryption and so often don’t have a need to configure encryption in individual services.

Huh, I thought that’s exactly what they do during a raid. TIL.
