Financial disclosures filed over the past year show that Rackspace Technology has continued to rack up expenses and losses following last year’s December ransomware attack on one of its hosted Microsoft Exchange servers. So far, the incident costs have soared well into eight figures.

Rackspace is a Texas-based, cloud computing services provider, largely for small and midsize businesses (SMBs), and declined to comment for this story on its financial statements. On December 2, 2022, a ransomware attack disrupted email services for thousands of its SMB customers by way of the ProxyLogOn zero-day vulnerability (CVE-2021-26855), which it had not patched due to operational concerns with the update.
