A cyberattack is like when someone tries to break into your house without your permission. A person or group of people can try to get into someone else's computer or network without their permission. Usually, the attackers will try to access information or do something harmful. They might try to steal information like credit card numbers, or they might try to delete important things like documents or photos. Cyberattacks can happen to anyone, no matter where they are or who they are.
