The court system, in a statement, said it doesn’t know who was behind the attack, why the court system was targeted or how long it will be before services are fully back online. It says it does not believe personal or confidential data was taken from the courts’ computer systems and says no credit card information was accessed.

Joel Bolger, the chief justice of the Alaska Supreme Court, last week told The Associated Press that the court system did not receive a ransom demand or any direct message from those involved in the cybersecurity attack.
