iOS 10.3.1 update prevents: attacker within range may be able to execute arbitrary code on the Wi-Fi chip

Hackers Are Emptying ATMs With a Single Drilled Hole and $15 Worth of Gear

  • NOT SO LONG ago, enterprising thieves who wanted to steal the entire contents of an ATM had to blow it up. Today, a more discreet sort of cash-machine burglar can walk away with an ATM’s stash and leave behind only a tell-tale three-inch hole in its front panel.

  • The dispenser will obey and dispense money, and it can all be done with a very simple microcomputer.

  • They found that the machine’s only encryption was a weak XOR cipher they were able to easily break, and that there was no real authentication between the machine’s modules

  • In practical terms, that means any part of the ATM could essentially send commands to any other part, allowing an attacker to spoof commands to the dispenser, giving them the appearance of coming from the ATM’s own trusted computer.
