Cass Balzer writes: “Ransomware attacks and cybersecurity incidents are no longer rare, with more than 15 million cyberattacks worldwide annually since 2020, and public institutions have become frequent targets. These attacks often shut down core systems, compromise personal information of patrons and library employees, and leave communities without access to certain services, all while demanding substantial resources to repair the damage. For libraries that have faced cyberattacks, recovery was often long, complicated, and costly, but their experiences offer lessons in how libraries can respond and rebuild.”
