Hackers Could Abuse Electric Car Chargers To Cripple the Grid, Researchers Say 126

alphadogg writes "Hackers could use vulnerable charging stations to prevent the charging of electric vehicles in a certain area, or possibly even use the vulnerabilities to cripple parts of the electricity grid, a security researcher said during the Hack in the Box conference in Amsterdam on Thursday. While electric cars and EV charging systems are still in their infancy, they could become a more common way to travel within the next 10 years. If that happens, it is important that the charging systems popping up in cities around the world are secure in order to prevent attackers from accessing and tempering with them, said Ofer Shezaf, of HP ArcSight. At the moment, they are not secure at all, he said."

This guy is just hyping up a non existent problem and turning it into "OMG terrorist hackers will cripple our country!" FUD. Its silly attention seeking.

      Example:
      If you had 10 chargers in a parking lot, each charger would have its own internal circuit breaker and the entire branch circuit that powers them all also must have a circuit breaker. Lets say the branch circuit can only support a maximum of 5 chargers at full power or a mix of low/high charge levels for all 10. If some "hacker" turned them all on at once guess what happens? The branch circuit breaker trips, problem solved. Even if there were 100 chargers, a breaker will trip and again problem solved.

If you machine the strip right, if it gets too hot it will flex away and break circuit contact! For extra safety, you could even design a catch system so that it can't automatically re-engage when it cools back down.
