Our increasing reliance on technology for education, administration, and communication comes with significant cyber security risks. One of the most pressing concerns facing education organisations is the theft of credentials - login information that enables unauthorised access to sensitive systems and data.
Let's explore the implications of stolen credentials in schools, common tactics used by cyber criminals, and best practices for protecting against this growing threat.
Understanding the impact of stolen credentials
Stolen credentials can lead to a range of harmful consequences for schools and Trusts, including data breaches, operational disruption, reputational damage and financial loss - our article exploring the Financial loss and impact of a cyber attack highlights just how serious things can become.
Common tactics used to steal credentials
Cyber criminals employ various methods to acquire stolen credentials, some of which include:Phishing Attacks: One of the most prevalent tactics where attackers send emails or messages that appear legitimate, tricking users into providing their login information. Phishing attacks often mimic well-known services, making them hard to detect.
Keylogging: Malicious software can be installed on a user's device to record keystrokes, capturing passwords as they are typed.
Data Breaches: When third-party services used by schools experience security breaches, login credentials can be leaked, giving attackers the opportunity to use that information in credential stuffing attacks.
Social Engineering: Attackers may manipulate individuals into revealing their credentials through phone calls or in-person interactions, often posing as IT support or school administration.

Best practices for protecting against credential theft
There's a whole range of proactive measures schools can take to safeguard against the threat of stolen credentials, here's our top 7:
1. Implement Multi-Factor Authentication (MFA): Adding an extra layer of security can significantly reduce the risk of unauthorised access. This requires users to provide additional verification (like a code sent to their mobile device) beyond their password.
2. Educate Staff and Students: Conduct regular training sessions on cybersecurity best practices, including how to recognise phishing attempts and the importance of safeguarding personal information.
3. Use Strong, Unique Passwords: Encourage the use of complex passwords and avoid reusing passwords across different accounts, or worse still using shared passwords! Provide staff with clear guidance on generating and managing unique passwords.
4. Regularly Monitor Accounts: Automated monitoring tools can detect suspicious login attempts and alert administrators to potential breaches.
5. Limit Access: Implement role-based access controls to ensure users only have access to the systems and data necessary for their specific roles. This minimises the potential impact of stolen credentials.
6. Conduct Security Audits: Regularly assess and update security practices and systems to identify vulnerabilities and ensure compliance with best practices.
7. Invest in Incident Response Planning: Develop a well-defined incident response plan that outlines steps to take in the event of a credential theft or data breach. Regularly review and practice the plan to ensure preparedness.
Conclusion
The threat of stolen credentials is not just a challenge for the IT department; it’s a concern that affects your entire school community. Protecting sensitive information and maintaining the integrity of educational systems must be a collective effort. By understanding the risks associated with stolen credentials and implementing robust cybersecurity measures, schools can better safeguard their data, protect their reputation, and create a safer learning environment for students and educators alike.
Cyber security, like data protection, is a journey, not a destination, and proactive measures today can pave the way for a more secure tomorrow.
