On October 29, 2022, the Atacama Large Millimeter/submillimeter Array (ALMA) suffered a cyber-attack on its computer systems, forcing the suspension of astronomical observations and the public website. This event is under investigation by local authorities.The Computing team quickly isolated the Antennas and Correlator systems and the Science Archive data systems. However, communication and other operational clusters were affected, forcing ALMA to stop all observations. Since then, email communication has been restored safely, along with new collaboration tools that enable the staff to continue their regular work.

The Crisis Management Team has developed a full-recovery plan in consultation with cyber security officers from ESO/NAOJ/NRAO. Our highest priority is to work hard to resume observations before the end of the year.

Further updates will be posted on the Science Portal when new information becomes available regarding return of services and operations.
