FedEx still on mend after cyberattack

Information systems in FedEx Corp.’s TNT unit may never fully recover from a June cyberattack, the company said in a statement Monday, and the amount of lost revenue was still being evaluated.

While TNT facilities are operating, customers are still experiencing “widespread” service and invoicing delays, FedEx said in its statement. A significant portion of TNT operations are using manual processes, the company said.

“We cannot yet estimate how long it will take to restore the systems that were impacted, and it is reasonably possible that TNT will be unable to fully restore all of the affected systems and recover all of the critical business data that was encrypted by the virus,” the Memphis-based courier said.

The Petya virus affected TNT through tax software used in Ukraine. Other operations haven’t been affected by the attack, said FedEx, owner of the world’s largest cargo airline. The company said it found no evidence of a data breach or data lost to third parties.

The June cyberattack demanded $300 in cryptocurrency to unlock infected computer networks. The virus spread throughout Europe before jumping to the U.S. and eventually reaching Asia and South America.
