Action Fraud have published an alert warning to schools reagrding a scam which tricks people into installing ransomware which then encrypts files on victim’s computers.
Fraudsters are initially cold calling education establishments claiming to be from the “Department of Education”. They then ask to be given the personal email and/or phone number of the head teacher/financial administrator. They then claim that they need to send guidance forms to the head teacher (these so far have varied from exam guidance to mental health assessments). The scammers on the phone will claim that they need to send these documents directly to the head teacher and not to a generic school inbox, using the argument that they contain sensitive information.
The emails will include an attachment – a .zip file (potentially masked as an Excel or Word document). This attachment will contain ransomware, that once downloaded will encrypt files and demand money (up to £8,000) to recover the files.
It should be noted that similar scam attempts have been made recently by fraudsters claiming to be from the Department for Work and Pensions and telecoms providers (in this case they need to speak to the head teacher about ‘internet systems’).
How to protect against this type of fraud
Having up-to-date virus protection is essential; however it will not always be able to prevent you from becoming infected.
Please consider the following actions:
- Although the scammers may know personal details about the head teacher and use these to convince you they are a real employee, be mindful of where these have been obtained from, are these listed on your school website?
- Please note that the “Department of Education” is not a real government department (the real name is the Department for Education).
- Don’t click on links or open any attachments you receive in unsolicited emails or SMS messages. Remember that fraudsters can ‘spoof’ an email address to make it look like one used by someone you trust. If you are unsure, check the email header to identify the true source of communication or contact them via a trusted point of contact e.g a nationally known number or email.
- Always install software updates as soon as they become available. Whether you are updating the operating system or an application, the update will often include fixes for critical security vulnerabilities.
- Create regular backups of your important files to an external hard drive, memory stick or online storage provider. It’s important that the device you back up to aren’t left.
