Update: We appreciate your patience as we continue to work through the security issues that have affected our Hosted Exchange environment. 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. We have since determined this suspicious activity was the result of a ransomware incident.
Alongside our internal security team, we have engaged a leading cyber defense firm to investigate. Our investigation is still in its early stages, and it is too early to say what, if any, data was affected. If we determine sensitive information was affected, we will notify customers as appropriate. Based on the investigation to date, we believe that this incident was isolated to our Hosted Exchange business. The Company's other products and services are fully operational, and we have not experienced any impact to our Rackspace Email product line and platform. Out of an abundance of caution, we have put additional security measures in place and will continue to actively monitor for any suspicious activity. https://www.bleepingcomputer.com/news/security/rackspace-confirms-outage-was-caused-by-ransomware-attack/ https://status.apps.rackspace.com/index/viewincidents?group=2 / Emil Stahl Pedersen Systems Engineer Office: +45 70 40 00 00 emil.st...@team.blue<mailto:emil.st...@team.blue> Operations Linux team.blue Denmark A/S H?jvangen 4 8660 Skanderborg Denmark CVR: 29412006 [cid:team.blue-color-rgb-small-mail-signature_78509216-de0a-4033-a847-aa8f4610dc1b.png] From: mailop <mailop-boun...@mailop.org> on behalf of William Kern via mailop <mailop@mailop.org> Date: Monday, 5 December 2022 at 23.17 To: mailop@mailop.org <mailop@mailop.org> Subject: Re: [mailop] RackSpace Security Issue thanks all, It seems we will all have to wait for the after action report to find out what really happened and what are the consequences. In the meantime, we can only express best wishes to the poor sysadmins at Rackspace who are not having a good weekend/week. -bill On 12/5/2022 1:22 PM, Louis Laureys via mailop wrote: This is the only thing I came across: https://cyberplace.social/@GossiTheDog/109446533829121659 Louis Op maandag 5 december 2022 om 19:50, schreef William Kern via mailop: I was contacted by a website customer over the weekend, who is affected by the RackSpace Exchange "security issue". At this point, they are transitioning to O365 so they should be fine going forward, but aside from email interruption they are not sure how they are affected. Their main concern is email disclosure. I'm trying to 'google' around but most of what I am finding are 'Rackspace is down' and complaints they aren't saying much. Does anyway have additional info? Since I also have customers who run their own Exchange servers, I'm curious if there is some new exploit out there, that they should be worried about.
