As a student, if you fall victim to a cyberattack, you need to tell someone about it, preferably someone older than you. Keep all the evidence that shows you were cyberattacked and report the matter to the nice educational centre administration as fast as possible as the educational centre will know how to assist you.
For the educational centre, it will need to involve their cyber insurance company to help with the matter. This will keep the whole thing from escalating and bringing much more extensive damage. The educational centre can also find the means to protect their students from cyberattacks.
