Calgary Public Library locations reopening Wednesday with modified service

The Calgary Public Librarysays all of its locations will reopen for regular hours on Wednesday after acybersecurity breach hit the library system on Friday.

The attack led to all CPL locations closing as of 5 p.m. Friday.All servers and library computer access were turned off.

"Data security is a key priority for the library and our security team is working to complete a thorough investigation," reads a statement from the CPL, issued Monday.

"While many services will not be available during this process, we are committed to providing critical access tolibrary spaces."

Patrons at the library on Wednesdaywill have access to library spaces and services that do not require technology, the CPL said.

Those services includeprograms and events that don't require technology, limited access to collection browsing, limited materials check-out and holds pickup, andlimited availability to study areas and drop-in meeting rooms.

Book returns, printing, digital library access, and online room booking and program registration are among the services that won't be available for the time being. The library said due dates for all borrowed materials will be extended until further notice.

The CPL said there's no timeline on when an investigation into the breach will be completed.

"We would like to thank ouremployees, volunteersand members for theirongoingsupport, understanding,and dedication," the statement reads.

Tom Keenan, a professor inthe school of architecture, planning and landscapeat the University of Calgary, previously told CBC News public institutions such as libraries are a logical target for cyber criminals.

"Almost everybody has a library card, it's free in Calgary, so there's a big database of people they can get," Keenansaid.

"And think about it. When you got your library card, what did you tell them? Your name, maybe your address, your email address. So there's a rich amount of data there and the bad guys go looking for things like that."

Late last year, acybersecurity incident disrupted Toronto Public Library services. Forensic investigators found the hackers stole the personal information of current and former staff members.
