Ukraine is hit hardest as nations consider cost

PARIS — Companies and governments around the world on Wednesday counted the cost of a software epidemic that has disrupted ports, hospitals and banks. Ukraine, which was hardest hit and where the attack likely originated, said it had secured critical state assets — though everyday life remained affected, with cash machines out of order and airport displays operating manually.

As the impact of the cyberattack that erupted Tuesday was still being measured, the Ukrainian Cabinet said that “all strategic assets, including those involved in protecting state security, are working normally.”

But that still left a large number of nonstrategic assets — including dozens of banks and other institutions — fighting to get back online. Cash machines in Kiev were still out of order Wednesday, and Ukrainian news reports said that flight information at the city’s Boryspil airport was being provided in manual mode.

Others outside Ukraine were struggling, too. Logistics firm FedEx said deliveries by its TNT Express subsidiary have been slowed by the cyberattack, which had significantly affected its systems.

At India’s largest container port, one of the terminals was idled by the malicious software. M.K. Sirkar, a manager at the Jawaharlal Nehru Port Trust in Mumbai, said no containers could be loaded or unloaded Wednesday at the terminal operated by A.P. MollerMaersk, the Denmark-based shipping giant.

At the very least, cybersecurity firms said thousands of computers worldwide have been struck by the malware.
