The Seattle Central Public Library has restored all services after a ransomware attack over Memorial Day weekend that severely disrupted operations across its 27 locations. The attack rendered public computers, online catalogs, e-books, and other essential services inaccessible, forcing staff to manually log book checkouts and finances. As of early September, public computers and services like item suggestions and pickup lockers are back online, with only microfilm access expected to be restored later this month. Library officials have implemented enhanced security measures, including multi-factor authentication and cloud migration, and are investigating the breach with forensic specialists. While some staff personal information may have been compromised, it remains unclear if patron data was affected. A report detailing the incident and response is anticipated by the end of the year.
