German Host Mittwald Shuts Down Management Services Again Following Cyberattacks
Mittwald disabled its customer center, mStudio, and SSH access on Nov 12 after attackers resumed operations following an initial breach via its MCP server interface.
German web hosting provider Mittwald shut down its customer center, administration interface mStudio, and all SSH connections again on November 12, 2026. This marks the second such outage within a week. The company had previously suffered a breach where attackers accessed customer projects through its Model Context Protocol (MCP) server interface by stealing user tokens.
According to reporting by TechGefrickel, Mittwald documented on its status page that attackers resumed their attacks on its infrastructure after last week's incidents, exploiting a vulnerability to compromise the company website. While Mittwald stated it has not yet found evidence of access to internal systems, the precautionary shutdown was implemented because the attackers appear to be professional actors using automated AI systems.
The disruption primarily affects agencies and freelancers who rely on Mittwald for hosting. Although customer websites and email services remain accessible, the lack of mStudio and SSH access prevents technical staff from performing deployments, domain changes, or database maintenance. Mittwald has not provided a timeline for restoring services, stating that further details will be released once countermeasures are complete.
