Why schools are ransomware targets
Schools combine high-PII (student records, parent payment data, safeguarding files) with often-poor backups and time-pressured leadership that may pay to restore service before exam periods. Attackers calibrate ransom demands to school budgets, typically lower than corporate ransoms but with much higher conversion rates.
How AI-native security prevents ransomware
Three layers, each catching ransomware at a different stage:
- Behavioural detection of encryption activity, Sophos CryptoGuard rolls back unauthorised encryption at the file system level.
- Anti-data-exfiltration, BlackFog stops the data-leak phase that precedes most modern ransomware. If data cannot leave the device, the double-extortion model breaks.
- Email-borne payload prevention, Coro AI Essentials catches AI-generated phishing carrying ransomware payloads.
Any one of these reduces the success rate; together, the compound effect is order-of-magnitude.
Backup and recovery strategy
The 3-2-1 rule still applies: three copies, two media, one off-site. The modern addition is immutable backups, copies that ransomware cannot encrypt. Test restoration quarterly; "we have backups" is not the same as "we can restore from backups".
What to do during an active attack
Isolate affected systems from the network. Preserve evidence, do not wipe machines until forensic capture is complete. Contact KB and law enforcement (NCSC in UK, ACSC in AU, NCSC in NZ). Coordinate communications via your governance protocol, staff, parents, regulators each get a different message at different times.
Frequently asked questions
Should schools pay the ransom?
Official guidance across all three regions is no. Payment funds further attacks, may have legal implications (sanctions exposure varies by attacker affiliation), and offers no guarantee of recovery. Decision should be made with legal counsel and law enforcement involvement.
How long does recovery take?
Depends on backup posture. With immutable backups and a tested restoration plan: 24-72 hours. Without: 1-3 weeks for a full school environment, sometimes longer.
Does cyber insurance cover this?
Most policies require basic AV plus MFA as a precondition. AI-native deployments often qualify for better rates and broader coverage. We can liaise with your insurer during scoping to confirm what their underwriter wants to see.
