Hm, in my experience the difference between idle and 100% CPU usage on a modern ARM processor (e.g. Allwinner H3) is around 1 Watt. That's more or less what an LCD monitor in standby draws.
I wouldn't call that significant (as in, impacting the global energy consumption significantly) even if thousands of devices started the attack at the same time.
- drvdevd 10y agoWould you call that detectable? Eespecially en masse. Perhaps a smart grid could detect these attacks in some way and dynamically adjust power to compromised devices?
- mjevans 10y agoI wouldn't. The signal ratio to noise very likely just isn't there. Remember, people regularly operate toaster ovens, microwaves, hairdryers, etc on a fluxuating basis, and THOSE tend to consume more like 1200+ Watts for a /single/ device.
