Texas-based cloud computing provider Rackspace has confirmed today that a ransomware attack is behind its ongoing Hosted Exchange outage.
"As you know, on Friday, December 2nd, 2022, we became aware of suspicious activity and immediately took proactive measures to isolate the Hosted Exchange environment to contain the incident," the company said in an update to the initial incident report.
"We have since determined this suspicious activity was the result of a ransomware incident."
Rackspace says that the investigation, led by a cyber defense firm and its own internal security team, is in its early stages with no info on "what, if any, data was affected."
The cloud service provider says it will notify customers if it finds evidence that the attackers gained access to their sensitive information.
"Based on the investigation to date, Rackspace Technology believes that this incident was isolated to its Hosted Exchange business," the company added in a press release.
"Rackspace Technology's other products and services are fully operational, and the company has not experienced an impact to its Email product line and platform."
UPDATE: Since becoming aware of suspicious activity in our Hosted Exchange environment on 12/2, we’ve determined that the isolated disruption is the result of ransomware and our security team is working with a lead cyber defense firm to investigate. Status:https://t.co/Uz0k8GL7Sg
