Remediation
Vendor solution
Arbiter Systems would like to stress that they have not heard of this vulnerability being exploited in an actual control system. They have created a new product line, the 1200 series, which is not vulnerable to this type of attack.
Arbiter Systems plans to continue to sell the 1094B model clock, because it is difficult to spoof the GPS signal and not likely to happen. In the unlikely event that the 1094B has been compromised, it can be recovered by removing and replacing the internal receiver battery. Arbiter Systems plans to investigate the feasibility of changing this model to protect against this type of exploit.
