The experiment used a computer program to rapidly open and close a diesel generator's circuit breakers out of phase from the rest of the grid and explode. This vulnerability is referred to as the Aurora Vulnerability.This vulnerability is especially a concern because much grid equipment supports using Modbus and other legacy communications protocols that were designed without security in mind. As such, they don't support authentication, confidentiality, or replay protection, which means any attacker that can communicate with the device can control it and use the Aurora Vulnerability to destroy it. This is a serious concern, as the failure of even a single generator could cause widespread outages and possibly cascading failure of the entire power grid, like what occurred in the Northeast blackout of 2003. Additionally, even if there are no outages from the removal of a single component (N-1 resilience), there is a large window for a second attack or failure, as it could take more than a year to replace it, because many generators and transformers are custom-built for the substation.The Aurora vulnerability can be mitigated by preventing the out-of-phase opening and closing of the breakers. Some suggested methods include adding functionality in protective relays to ensure synchronism and adding a time delay for closing breakers."@en }
