SFUSD Schools Closed After Ransomware Attack
Locales: California, UNITED STATES

San Francisco, CA - February 21, 2026 - All schools within the San Francisco Unified School District (SFUSD) were unexpectedly closed today, Saturday, February 21st, 2026, following a confirmed ransomware attack targeting the district's IT infrastructure. The closure impacts all students and staff, with district offices also shuttered as officials scramble to contain the breach and assess the extent of the damage.
The SFUSD publicly announced the incident late Friday, stating they were "aware of a ransomware attack impacting district IT systems." The decision to immediately close schools was made as a precautionary measure to prevent further disruption and safeguard sensitive information. This isn't an isolated incident; school districts across the nation have increasingly become targets for cyberattacks, highlighting a growing vulnerability in the education sector.
While the immediate priority is system restoration and a return to normalcy, the SFUSD has assured parents and guardians that, as of now, there is no evidence that student or staff data has been compromised. However, cybersecurity experts caution that the absence of immediate data breach confirmation doesn't guarantee future security. Ransomware attacks often involve a delayed data exfiltration component, meaning attackers may have already copied sensitive data before encrypting systems and demanding a ransom.
"This is a developing situation, and we are working diligently with law enforcement and leading cybersecurity firms to investigate the source of the attack, mitigate its impact, and restore our systems as quickly and safely as possible," the district statement read. Specific details regarding the type of ransomware used and the attackers' demands remain undisclosed to avoid potentially jeopardizing the investigation.
A Growing Trend: Ransomware Attacks on Schools
The SFUSD attack joins a worrying trend of cyberattacks targeting educational institutions. Schools are attractive targets for several reasons. They often lack the robust cybersecurity infrastructure of larger corporations or government agencies due to budget constraints. They also possess a wealth of personally identifiable information (PII) - including student records, staff data, financial information, and health records - which can be valuable on the dark web. The urgency and high-stakes nature of ensuring children's education also makes schools more likely to pay ransoms to quickly restore access to critical systems.
According to recent data from the K-12 Cybersecurity Resource Center, ransomware incidents impacting schools have increased by over 75% in the past two years. These attacks can range from simple data encryption to the public release of sensitive information, causing significant reputational damage and potential legal ramifications. The cost of remediation, including system recovery, legal fees, and potential fines, can also be substantial.
What's Next for SFUSD? The district has pledged to provide a more detailed update on the situation on Monday, February 24, 2026. This update is expected to include information regarding the investigation's progress, a timeline for system restoration, and any potential impact on upcoming school events or schedules. Parents are advised to check the SFUSD website and social media channels for the latest information.
Beyond the immediate crisis, the SFUSD will likely face increased scrutiny regarding its cybersecurity protocols. Experts recommend a comprehensive review of the district's IT infrastructure, including regular security audits, employee training on phishing and malware awareness, and implementation of multi-factor authentication. Investing in advanced threat detection and response systems is also crucial to proactively identify and mitigate future threats.
The incident also raises questions about data backup and disaster recovery plans. A robust backup strategy, with data stored offline and securely, can significantly reduce the impact of a ransomware attack by allowing the district to restore systems without paying a ransom. Furthermore, the district may need to collaborate with other school districts and government agencies to share threat intelligence and best practices.
This attack serves as a stark reminder that cybersecurity is a critical issue facing educational institutions today. Protecting student and staff data, and ensuring uninterrupted access to essential learning resources, requires a proactive and comprehensive approach to cybersecurity.
