Does being at low battery make attacks against the device easier? Seems like it does from the report here but i'm not sure why.

- lazide 5y agoSpeculation - maybe it turns off some rate limiting, or disables some sanity checking that is more CPU/energy intensive or similar?
- kadoban 5y agoI read that as just being a list of what circumstances you can still use the attack that you might otherwise think you couldn't. For example having a broken screen it seems clear couldn't provide any benefit, but that's also in that same list.
- alias_neo 5y agoI too wondered why this is significant, couldn't you simply charge the device first? Wouldn't it be charging while connected to the GreyKey?
- Anunayj 5y agoI remember seeing a similar attack on iphones before. What I understood was it cutoff the power to the device before the TPM could log a passcode attempt. This [1] seems to be similar to what I remember. [1] https://techcrunch.com/2015/03/19/iphone-bruteforce-pin/ https://techcrunch.com/2015/03/19/iphone-bruteforce-pin/
