Security breach with Mavericks
I just got an email listing the only two computers in the network with OS 10.9.1 loaded. It was from a company called Orbicule which listed the computers and their serial numbers. I am not sure if this is because we had Firewall not set or just a bad idea for a marketing campaign, but I would like to know if it is a system vulnerability?
OS X Mavericks (10.9.1)
