Calgary Public Library officials are expected to provide an update on the recent ransomware attack that targeted the facility’s computer systems this month.

All libraries were closed from October 11 to 16 following a cybersecurity breach.

Officials say the attack was blocked and the library’s servers were shut down as a precaution.

All locations have since been reopened and all due dates for borrowed materials have been adjusted until further notice.

The library has not said whether the attackers accessed any customer information.

The update is expected at 10 am.
