This part was interesting: "Bednarek then tried putting a dollar into a new, previously unused weak key address. It, too, was emptied in seconds, this time transferred into an account that held just a few thousand dollars worth of ether. But Bednarek could see in the pending transactions on the Ethereum blockchain that the more successful ether bandit had attempted to grab it as well. Someone had beaten him to it by mere milliseconds." [emphasis mine]
It seems like there is an arms race of Blockchain Bandits leading to HFC-like systems aiming to try out as many generic private keys as possible as quickly as possible.
