The Battle Against School Phishing And Ransomware Issues

The increasing frequency of cyber threats, particularly phishing and ransomware attacks, poses a significant challenge for educational institutions. Between 2016 and 2022, public K-12 schools experienced over 1,600 cyber incidents, with more than 50 reported ransomware attacks annually. A recent attack on a New Haven school, resulting in a $6 million loss, highlights the vulnerability of schools to cyber criminals exploiting email exchanges. The attractiveness of schools as ransomware targets stems from their possession of valuable data, limited budgets, diverse user bases, and decentralized IT systems. Internal threats, including pranks by students, further emphasize the need for comprehensive security solutions. Various cyber threats, such as email phishing, spear phishing, whaling, vishing, and smishing, continually challenge school IT administrators, requiring constant vigilance and proactive measures. Implementing robust cyber security practices, including awareness training, technological fortifications, and vigilant response strategies, is crucial for safeguarding schools against evolving cyber threats. The battle against these issues necessitates ongoing attention, adaptation to emerging threats, and the implementation of effective cyber security protocols to create a secure digital environment for students, educators, and staff.

Schools are facing a rising number of cyber threats, especially phishing and ransomware attacks. From 2016 to 2022, there were over 1,600 cyber incidents targeting public K-12 schools, with more than 50 reported ransomware attacks each year. A recent attack on a New Haven school highlighted the seriousness of the issue, where cyber criminals stole $6 million by exploiting email exchanges between the COO, the city’s budget office, and vendors. They impersonated the COO for six fraudulent transfers. Ransomware and phishing pose significant challenges for schools, administrators, and their IT departments.

Why educational institutions are targeted by ransomware?

Schools and universities have become increasingly attractive targets for ransomware attacks in recent years. These institutions often possess a unique combination of factors that make them vulnerable:

1. Valuable Data: Educational institutions hold a wealth of sensitive data, including student records, financial information, and research data. This information can be incredibly valuable to cyber criminals who can sell it on the dark web or use it for identity theft.
2. Limited IT Resources: Many schools and universities have limited IT budgets and staff, making it difficult for them to invest in robust cyber security measures. This lack of resources can make it easier for attackers to target and exploit vulnerabilities.
3. Pressure to Pay: Schools and universities often feel pressure to pay ransoms quickly to minimize disruption to their operations and protect sensitive data. This can make them more likely to give in to attacker demands.
4. Outdated Systems: Many educational institutions still rely on outdated IT systems that are vulnerable to attack. This is especially true for smaller schools and districts that may not have the resources to upgrade their technology.

The consequences of a ransomware attack on an educational institution can be severe. In addition to the financial losses, these attacks can also disrupt classes, damage the institution’s reputation, and put students’ personal information at risk.
Schools are often targeted by ransomware attacks because they are considered easy targets. The presence of valuable personal data and insufficient security measures make them attractive to attackers. Surprisingly, some threats come from within, with students attempting pranks or vandalism.
This emphasizes the need for comprehensive security solutions that address both external and internal risks. To understand the cyber security risks faced by regular schools and K-12 institutions, it’s important to consider factors like valuable data, limited budgets, a diverse user base, decentralized IT systems, lack of cyber security expertise, and the challenges posed by remote learning and BYOD (Bring Your Own Device).

Type of threats currently impacting schools
Schools encounter various cyber threats, and it’s not just limited to phishing or ransomware. IT administrators need to stay alert because cyber criminals are always coming up with new ways to infiltrate systems.

1. Email phishing
This is a deceptive tactic where cyber criminals send emails pretending to be trustworthy sources to extract personal information. These malicious emails often contain links or downloads that, when clicked, can infect systems or steal data.

2. Spear phishing, or targeted email phishing
Taking regular phishing a step further, spear phishing involves carefully crafting emails to target specific individuals or organizations. Personalizing the attack increases its success rate, making it highly dangerous.

3. Whaling, or targeted emails impersonating a senior player at an organization
Whaling is a sophisticated form of spear phishing that focuses on top-tier executives. The New Haven crisis is a classic example where cyber criminals impersonated a senior executive, resulting in significant financial losses. There are multiple instances of successful whaling attacks in schools.

4. Vishing or phone call phishing
Vishing is the telephone version of email phishing, where scammers pretend to be legitimate entities over the phone. With AI-trained voices, cyber criminals are now creating more convincing and deceptive calls, raising the stakes.

5. Smishing, or phishing by SMS text
Smishing uses text messages to deceive recipients. Cyber criminals send texts prompting recipients to click links or call numbers, leading to potential data theft or system compromise.

Protecting the Classroom: Best Practices for Keeping Schools Secure from Cyber Threats

1. Laying the Foundation: Awareness and Training
Everyone in the school community, from students to janitors, needs to understand basic cyber security concepts and how to spot suspicious activity. Regular training sessions and awareness campaigns can equip everyone with the knowledge and vigilance to be the first line of defense.
Age-appropriate cyber security lessons can be incorporated into curriculums to instill good digital hygiene habits from a young age. Think fun quizzes, interactive games, and engaging activities that make learning about online safety enjoyable.

2. Fortifying the Walls: Robust Technology and Policies
Invest in strong firewalls and antivirus software. These act as gatekeepers, filtering out malicious traffic and protecting your network from unwanted intrusions. Regularly update these defenses to stay ahead of evolving cyber threats.

• Implement strict password policies. Enforce strong password requirements (length, complexity, no personal information) and regular password changes. Consider multi-factor authentication for added security.
• Secure your Wi-Fi networks. Use separate networks for students, staff, and guests, and encrypt them with strong passwords. Monitor network activity for suspicious behavior.

3. Building a Watchtower: Vigilance and Response
Monitor your systems for suspicious activity. Look for unusual login attempts, changes in user behavior, or spikes in network traffic. Early detection can help prevent serious damage.

• Have a clear incident response plan. Everyone in the school community should know what to do in case of a cyberattack. This plan should include steps for containment, communication, and recovery.
• Partner with cyber security experts. Don’t try to go it alone. Seek help from qualified cyber security professionals who can assess your vulnerabilities, implement security measures, and provide ongoing support.

Conclusion

The battle against school phishing and ransomware issues is an ongoing challenge that demands unwavering attention and proactive measures from educational institutions. The surge in cyber threats, including sophisticated techniques like spear phishing and whaling, underscores the need for comprehensive security solutions. The vulnerabilities arising from valuable data, limited budgets, diverse user bases, decentralized IT systems, and a lack of cyber security expertise make schools soft targets.
School administrators and IT departments must stay vigilant, adapt to evolving cyber criminal strategies, and implement robust cyber security protocols. By addressing these issues head-on, schools can fortify their defences, safeguard sensitive information, and create a secure digital environment for students, educators, and staff.
