Armis labs revealed a new attack vector that exposes millions of devices that use bluetooth. The attack is as close to actual airborne virus in the computer world that you can imagine. This story is so under reported due to other recent news stories (Equifax, Hurricane Irma, etc,.) it may catch a lot of folks off guard. What is scary about this attack is the sheer number of devices affected. Phones, Smart TV's, Smart appliances, unpatched computers systems. Nearly any device that has bluetooth. You can imagine this list is very long.

UPDATE: Samsung has begun pushing out updates on Verizon via OTA. I am sure all the other vendors will quickly follow suit.
