- There's a fascinating and redacted interview with an "anonymous" subject about the disaster. To say the least it's an unsuccessful attempt to hide the identity of the individual:
"Q. So how did you get yourself started into submersible operations?
A. Well, I'm sure you're familiar with my film Titanic. When I set down the path to make that film, the first thing that I did was arrange to be introduced to the head of the submersible program at the P.P. Shirshov Institute in Moscow, a guy named..."

- The SD card on the camera was intact but encrypted. Decrypting the data required a key stored on a separate SOM board, but the SOM was damaged. The investigation team delivered the SOM and SD card to the camera manufacturer in Newfoundland, and they were able to decrypt the card.
They found a couple of images, but
No data with a timestamp after May 16th was found on the camera, so it is likely that none of the data recorded on the SD Card were of the accident voyage or dive.
After all that work...If you're interested in data recovery, you will enjoy reading this report, about 10 pages, clearly written. The technical language mentioned they didn't see a LUKS header on the card so they figured it was a custom dm_crypt setup.
- Wow. SubC’s software engineering needs some work. They thought the camera’s file system was unencrypted, when it was encrypted. They didn’t know where the keys were to decrypt it. It turned out the key was written unencrypted to a UFS storage device. There was a file written to /mnt/nas/Stills, which indicates that the camera was to writing to a remote file system that wasn’t mounted.

- > Removed SD card. The manufacturer of the camera had requested certain components of
the device be redacted. Portions of this image have been redacted.
And so it is, but anyone who has ever seen a Sandisk SD card knows what they're looking at. I can even tell it's not the fastest V90 speed.
The things companies try ineffectually to keep out of public view are weird.

- Amusing that the bits the “manufacturer asked to be redacted” in the images appear to be the identifiers for common off-the-shelf electronic components, including a standard memory card. Is that really super secret IP?
- Crazy that it's pretty much a 3D printed assembly internally, and the manufacturer didn't know how it worked. No way that would pass any kind of vibration test.

- I'm confused. Why are decryption keys in NVRAM? That seems to negate the purpose of at-rest encryption if you can retrieve keys from the device even after shutdown.
- What's with the entire dev board crammed in there? Is that... normal? What board is it?
