After the attack comes the bill: Ransomware and data-exfiltration attacks continue to stick victims with serious cleanup, legal and other costs.

Cloud computing giant Rackspace has so far spent $10.8 million responding to an attack against its hosted Exchange environment by the Play ransomware group that began late last November, the company said in an earnings presentation released earlier this month. The attack, which came to light on Dec. 1, 2022, affected 30,000 Rackspace customers, leaving them unable to access to email and associated data.
