A ransomware virus attack on the Westchester Library System is being investigated, an IT official said in July.
Public access PCs were turned off temporarily as a precaution and restored to service on Friday, July 5 and Saturday, July 6.
In a public statement to library system patrons, WLS announced that the "virus disabled servers that control services used by PCs such as network management, printing and authentication."
"The server that contains patron data, the circulation system and online catalog was not impacted by this event and no data breach is suspected," the announcement said. "Public WiFi and online resources were also unaffected."
Public access PCs were turned off as a precaution and IT staff later restored these services.
"Following recovery from this event WLS will be working with local authorities to see what appropriate actions can be taken," the public statement said.
