Unknown number of vessels on an attack vector, coming in at high speed, proximity distance!
And so the danger is that it's sort of sitting there, really not being necessary, yet still representing an attack vector for people's machines.
In effect, you may be at a higher risk of attack due to the increased attack vectors.
The trojan does not use this attack vector for all banks, however.
Amazing how many things are becoming attack vectors with the proliferation of electronics.
Having an additional attack vector certainly isn't good though.
Of course you can have an attack vector that uses physical access to the machine to generate an exploit.
For each class, a specific attack vector is described here.
It is just an attack vector and most things don't use java anymore.
You've probably seen this already, but another attack vector has been proven exploitable.
