OpenSesame is a device that can wirelessly open virtually any fixed-code garage door in seconds.
If you are using a gate or garage which uses “fixed codes”, to prevent this type of attack, ensure you upgrade to a system which clearly states that it’s using rolling codes, hopping codes, Security+ or Intellicode. These are not foolproof from attack, but do prevent the OpenSesame attack along with traditional brute forcing attacks. Suggested vendors: current products from LiftMaster and Genie.
