HPE has confirmed that a “limited subset” of customer data was taken in a data breach involving its subsidiary Aruba Networks, a maker of networking equipment.

The enterprise technology giant said in a statement that an unauthorized person used a private key to gain access to customer data stored in its Aruba Central cloud. HPE did not say how the hacker obtained the private key, but said the key allowed access to cloud servers in multiple regions where customer data was stored.
