Diebold Nixdorf admitted a cyber attack on a service provider in a letter to customers, this provided optimization data for cash distribution to the ATMs.
It is uncertain who was responsible for the attack on servers and other components at the data center utilized by the service provider Planfocus.
Aside from not being impacted, neither customer data nor statistics data have been lost as of this writing, as far as is known.
A service provider's data center, which houses the CCO systems, was the target of the attack. Only the attack, not the cash supply itself, could have put the optimization in jeopardy.
