Comment Comment by RandomBK 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.[0] https://data.ntsb.gov/Docket/Document/docBLOB?ID=18741602&Fi... parent RandomBK 1 year ago
