Jackpotting: hackers are making ATMs give away cash

Two of world's largest cash machine makers and US Secret Service warn of attacks that empty ATMs at rate of 40 notes per 20 seconds

Cybercriminals are hacking cash machines to force them to give out money in what is known as "jackpotting", according to two of the world's largest ATM makers and the US Secret Service.

Diebold Nixdorf and NCR sent out an alert to their customers over the weekend, but did not identify victims or specify how much money had been stolen. The US Secret Service started warning financial institutions that jackpotting was now a risk in the US last week, having started in Mexico last year, according to a confidental alert seen by Krebs on Security.
