Imagine these being swapped out for the normal cables at an airport or mall "charging" station .. hundreds of people using those cables every day for charging .. all easily compromised..
Now that I think of it, the charging sockets themselves on airport benches or on the dedicated desks could also be compromised easily. Is there a way to detect something fishy is happening?
Since the implant can be reached remotely another attack would be simply to passively collect the data being transferred between a laptop and an external device.
