- Ekaros 4y agoI wonder do those meters have remote software update. And if so when we will see hack where as many as possible of them are bricked... Requiring massive operation to reconnect and replace each...
- Scoundreller 4y agoJumper cables: not just for cars! (don't do this)
- Mvandenbergh 4y agoThe architecture of the GB smart grid only allows any given meter to be remotely disconnected on certain days. This is to make it impossible for an attack to disconnect more than a fraction of all meters with any one attack.
- bmitc 4y agoWhat is the mechanism by which this is allowed or disallowed? Could that also not be hacked?
- cozzyd 4y agoMaybe downlinks can only be sent as a response to uplinks (similar to LoRaWAN class A?) and uplinks are every few days?
- cjrp 4y agoSo it's a two-stage attack; increase the frequency of up/downlinks, and then send the bricking payload!
- Mvandenbergh 4y agoIt's built into the meters based on a hardware ID code, so any particular meter will only accept a certain set of highly sensitive operations on particular days. So if you need to shut off Mrs. Miggins for non-payment (not legal to do remotely without sending an engineer at present but technically possible) or switch her meter to pre-pay (which is legal) then that command might only be acceptable to the meter once every 20 days. That does mean you can't immediately do it if you're the supplier but also limits the damage that a catastrophic compromise of the smart metering security system can do.
