Hacker Pilfers Client Data From Charles River Labs

May 9, 2019

A “highly sophisticated, well-resourced” hacker recently made off with some of Charles River Laboratories’ client data, the contract research organization reported.

On April 30, the company informed clients that parts of its information systems were accessed by an unauthorized intruder. Upon noticing “unusual activity” in mid-March, Charles River launched an investigation with the help of federal law enforcement and cybersecurity experts that is still ongoing.

Some client data was taken during the March breach, the company said, but it noted that there is ’s no evidence at this time showing the data was deleted, altered or corrupted.

“The number of clients whose data is known to have been copied represents approximately one percent of Charles River’s total number of clients,” the company said.
