TNT Express is still processing parcels manually nearly a month after it was hit by a worldwide cyber attack, and has predicted it may not be able to recover the data lost in the incident.

The FedEx-owned operator was hit with the NotPetya encryption virus on 28 June.

In a trading update on 17 July, FedEx said the virus hit TNT operations in Ukraine, thought to be the target of the attack, which allowed it to access the business’s data worldwide.

Fedex said: “Customers are still experiencing widespread service and invoicing delays, and manual processes are being used to facilitate a significant portion of TNT operations and customer services.”

It added it was “reasonably possible” that TNT wouldn’t be able to “fully restore all of the affected systems and recover all of the critical business data that was encrypted by the virus”.

FedEx has not yet been able to estimate the cost of the attack on the business, but has predicted that it will be “material”.

It added it did not have insurance to cover the cost of the attack.

“For about three weeks you couldn’t even speak to anyone on the phone, because it took their phones down. You couldn’t email them.”
