Cyber Crooks Wage War on Schools: Over a Third of English Schools Hit by Cyberattacks in the Past Year

Cybercriminals are increasingly targeting schools in England, with more than a third suffering crippling cyberattacks in the last year. According to officials, education institutions are struggling to protect students’ data amid a surge in hacking attempts. In 2023 alone, 347 schools were hit by cyber incidents, with the average ransom payment reaching £5.1 million and post-incident costs averaging £3 million per attack.

Despite repeated warnings since 2020, Jisc (the UK’s education technology provider) has failed to secure exposed internet assets, leaving thousands of schools and millions of pupils vulnerable. Shockingly, Jisc even threatened legal action against security experts who reported these vulnerabilities.

The National Cyber Security Centre (NCSC) and the Information Commissioner’s Office (ICO) have also been criticized for negligence in addressing these systemic security failures.

You Should Know: Critical Cybersecurity Practices for Schools & Organizations

1. Secure DNS & Network Configurations

• Check DNS vulnerabilities using tools like `dig` or nslookup:

  dig example.com ANY
  nslookup -type=any example.com
  

• Block unauthorized DNS requests using firewall rules:

  iptables -A INPUT -p udp --dport 53 -j DROP  Block external DNS queries
  

2. Prevent Ransomware Attacks

• Disable SMBv1 (common ransomware vector) on Windows:

  Disable-WindowsOptionalFeature -Online -FeatureName smb1protocol
  

• Enable Controlled Folder Access (Windows Defender):

  Set-MpPreference -EnableControlledFolderAccess Enabled
  

3. Detect & Mitigate Breaches

• Monitor suspicious logins on Linux:

  grep "Failed password" /var/log/auth.log  Check SSH brute-force attempts
  

• Isolate compromised systems quickly:

  ifconfig eth0 down  Disable network interface
  

4. Patch Management

• Automate updates on Linux:

  sudo apt update && sudo apt upgrade -y  Debian/Ubuntu
  sudo yum update -y  RHEL/CentOS
  

5. Backup Critical Data

• Encrypt backups before storage:

  tar -czvf school_data.tar.gz /var/www/ && gpg -c school_data.tar.gz
  

What Undercode Say

The negligence in securing school systems is unacceptable. Basic cybersecurity measures—like patching, DNS hardening, and ransomware prevention—could mitigate most attacks. The UK government and Jisc must act immediately to protect students’ data.

Key Commands to Enhance Security:

• Scan for open ports (Nmap):

  nmap -sV -T4 target_school.gov.uk
  

• Check for malware (ClamAV):

  sudo clamscan -r /home/
  

• Audit user permissions (Linux):

  sudo find / -perm -4000 -type f -exec ls -ld {} \;  Find SUID files
  

Expected Output: A hardened, monitored, and resilient IT infrastructure that prevents cybercriminals from exploiting schools.
