The slow bruteforcers may in fact be learning

badger.foo writes: "We've seen stories about the slow bruteforcers, and based on the data, my colleague Egil Möller was the first to suggest that since we know the attempts are coordinated, it is not too far fetched to assume that the controlling system measures the rates of success for each of the chosen targets and allocates resources accordingly. If Egil's assumption is right, we are seeing the bad guys adapting. And they're avoiding OpenBSD machines."
