…there are some technical tricks to retrieve RAM values after power loss
Do these tricks still work? Did they ever work or is it more internet rumor? Modern RAM refreshes itself really quickly and I suspect signal degradation happens more quickly than historical modules.
If you are worried about the gestapo seizing your servers and freezing the RAM, is there any mitigation in place?
- cyberpunk 2y agoI think it’s pretty much infeasible. Some professor did it in a lab once but I can’t see that level of sophistication being used against a public vpn server, whatever the circumstances. SGX encrypted memory would work as a solution for this, probably.
- reginald78 2y agoIt's been awhile since I read about this, but I remember the discharge time of the tested ram was so slow it seemed like anyone reasonably quick and prepared could potentially pull it off, even without freezing. But it was with SDR or DDR and modern ram discharge is so much quicker it is basically impossible now.
- GTP 2y agoIf they are determined, they can still seize the machines without powering them down. It has already been done in the past.
- 0cf8612b2e1e 2y agoI was imagining more the scenario that gman appears and you hastily flip the switch. I have so little trust in computer security I assume the powers that be have a USB stick with 0 days that can compromise any modern OS by just plugging into an active machine.
