Educational institutions have become the primary target of ransomware attackers due to their exposed security protocols. A dramatic surge in such attacks on schools confirms this theory. For instance, confidential documents from 14 academic institutions recently trickled into the public domain after a security breach. Hackers are increasingly targeting school districts and associations through ransomware for several reasons. Less-than-mature security postures, fewer grants, and narrow controls over sensitive data open the floodgates and make it easier for attackers to steal sensitive data.
This article will look at how ransomware attacks on schools can disrupt the regular workflow of educational institutions, as well as various preventive measures school administrators should take to protect their resources against ransomware.
Why are ransomware attacks on schools spiking?
Ransomware is malicious software that infects the target system and encrypts all files, thereby blocking access to them. Once they have prevented owners or organizations from being able to utilize their systems or data, attackers then demand a ransom payment in exchange for restoring access.
What are the challenges of ransomware attacks on schools?
Cybercriminals target schools for academic and other data of students, staff, and institutions. As most of these institutions lack the budget to invest in sound defence strategies, it becomes easy for cybercriminals to access school systems. The State of Ransomware report, 2021 (by Sophos) found that educational institutions and schools suffer the most ransomware attacks. According to them, 44% of respondents in the sector suffered a ransomware attack last year. Also, during these ransomware attacks, the malicious players hit a bonus. They could access students' and teachers' personal information. It becomes easy for scammers and identity thieves to leverage students' personal information for malicious activities.
Filter out malware: Malware is a catch-all term. Ransomware is a type of malware. School districts and associations should deploy anti-malware and network packet filtering tools to protect the entire system from contamination. Effective filtering criteria can help shield school administrators and students from ransomware when visiting websites that distribute or release malicious code.
Limit the use of peripheral storage devices and administrative accounts: Due to budgetary constraints, school and district IT staff encounter several challenges in staying in sync with evolving technologies. So, to minimize the risks of leveraging new technologies, school authorities should take proactive measures such as disallowing outside devices in office systems. The school executives and head should impose strict rules, restricting administrative access to a select few. Schools should also limit internet-exposed services like Remote Desktop Protocols (RDP).
Set security policies for office system use: It is essential to preserve cyber hygiene in school systems to protect against ransomware attacks. Anyone using office systems must follow protocols (mentioned in policies) for security reasons. Strict security policies must be in place. A few are:
Leveraging multi-factor authentication (MFA) to defend accounts against compromised passwords
Not injecting flash drives in office systems
Using strong passwords
Keeping systems and apps up to date
Backup system data and critical files: There is no guarantee that you can protect your school systems from sophisticated ransomware attacks. So, it is always better to back up critical data, including those of students and teachers. This way, even if ransomware attacks the systems and encrypts all files, you can format the entire system and restore the backup files from the stored repository. It is essential to isolate the data backup somewhere safe.
Educate everyone about cybersecurity: Educate school members (principals, superintendents, students, teachers, and other office staff) not to open malicious attachments, malicious sites, or unknown links. Also, schools should hire security professionals to train their employees to respond actively to cyber threats and events.
By conducting penetration testing, schools can fortify their security against potential threats and significantly reduce ransomware attacks. These tests will also help identify any weaknesses in the school's current system.
Ransomware is a growing threat to schools and academic institutions. It can cause severe damage not only to the school's data but also to students' information. To protect against ransomware attacks, it is essential for school authorities to deploy sound security strategies. Schools should limit access to computers, implement strict security policies, filter out malware and other malicious threats, and educate their members on cybersecurity. Finally, they should back up data regularly to prevent any loss of information due to ransomware attacks. With these proactive measures in place, schools can ensure the safety of their systems and data.
Ransomware Penetration Testing
Ransomware penetration testing evaluates the preparedness and risk of a ransomware attack. In addition to a complete analysis of the security program against the Cybersecurity Framework Profile for Ransomware Risk Management (NISTIR 8374), and a technical assessment of security controls, a full penetration test is conducted to measure the robustness of your systems.
