- I see a lot of discussion in this thread stemming from some confusion+not reading the actual report[0].
Some key points:
1. The Camera+Card was encased in a separate enclosure made of titanium+sapphire, and did not seem to be exposed to extreme pressures.
2. The encryption was done via a variant of LUKS/dm-crypt, with the key stored on the NVRAM of a chip (Edited; not in TrustZone).
3. The recovery was done by transplanting the original chip onto a new working board. No manufacturer backdoors or other hidden mechanisms were used.
4. Interestingly, the camera vendor didn't seem to realize there was any encryption at all.

- The NTSB's original report has more detail on how the SD Card was encrypted and how the NTSB managed to decrypt it:

- > No deep-sea shenanigans around the Titanic wreck were revealed. Manley explains in his Twitter thread that “the camera had been configured to dump data onto an external storage device, so nothing was found from the accident dive.” Nothing particularly pertinent to the tragic accident, that is.
This is about camera hardware and how it survived. It provides no information or footage about the incident (in case you were looking for it like I was).
- Scott Manley’s 45 minute video covering the NTSB report this information comes from went up today, it’s quite interesting.

- If a hardened camera can survive, I'm surprised subs don't have a floating black box that can survive an implosion and then float to the surface and begin emitting a radio signal.
I guess the trick would be finding a way to securely attach the black box in a way that would ensure its release in a catastrophic disaster.
- Figure 3 from the report- that's an Adafruit sensor module on a 3d printed bit of plastic with a teensy-brand microcontroller just sitting in there! Actually, the entire electronics enclosure appears printed.
Very funny to see in what I assume is a million-dollar product.

- It continues to amaze me how indestructible SDCards are.
- Since not everyone reads articles:
> Somewhat disappointingly, the images and videos shared in the report were taken in the vicinity of the ROV shop at the Marine Institute, also in Newfoundland. The location was the logistical base for Titanic dive missions. No deep-sea shenanigans around the Titanic wreck were revealed.

- is this a common setup to have the camera store to external storage device without storing to the SD card as well?

- also basically if enough companies agrees on helping the cause your crypto secrets are quite more likely to be exposed...
- but what about the Logitech controller?
- It might be advertising, but I'll allow it because it's so metal
- But how did anyone figure out it was a SanDisk SD card? Card details were redacted.

- What I also learned from this article is that Scott Manley is still on Twitter.
