Update: All St. Louis Public Library services have returned to full function after the Jan. 19 ransomware attack, a press release from the library said Monday. 

The release said most services were returned in a few days, but free printing services were the last to return. 

Bandura — a St. Louis Cybersecurity company — volunteered its services to the library system to ad a "sophisticated new layer of protection" to their system.


The St. Louis Public Library computer system has been hit with a ransomware attack.

Jen Hatton, PR manager for the library system, says a hacker organization has blocked their server and is demanding tens of thousands of dollars to release their computers back to them.

The attack has affected all 700 computers at 16 library branches.

No library visitors can currently use the computers until the problem is solved. The library's technology staff is working with the FBI.

While the computer system is down, patrons are also not able to check out books.
