Incident Details
The expenses incurred by Rackspace as a result of a ransomware attack last year are continuing to increase. The company, known for cloud hosting services, informed the U.S. Securities and Exchange Commission that the total costs related to the cyberattack have now surpassed $12 million. The attack, which targeted Rackspace's hosted Microsoft Exchange on December 2, 2022, was initially labeled as a "security incident" and led to the disruption of email services for numerous customers, primarily small and medium-sized businesses. After four days, it was confirmed that the cause of the email disruption was a ransomware infection, which lasted until January. Rackspace attributed the breach to the Play group, stating that the perpetrators gained unauthorized access by exploiting a critical Exchange privilege escalation vulnerability, CVE-2022-41080, before a patch was released by Microsoft.
