Operations at one of three terminals at India's largest container port JNPT, on the outskirts of India's commercial hub of Mumbai, have been disrupted by the global ransomware attack.
The terminal impacted is operated by Danish shipping giant AP Moller-Maersk, which said that the cyberattack had caused outages in its computer systems globally.
The attack, similar to the ransomware that infected more than 3,00,000 computers last month, also affected computers at Russia's biggest oil company, Ukranian banks, and multinational firms.
The Indian port has been trying to clear containers manually, but operational capacity has dropped to a third at the terminal, Anil Diggikar, Chairman of Jawaharlal Nehru Port (JNPT), told.
"This is fallout of global cyber attack. We are hopeful that operations will normalise in a day," he said. "Containers are piling up outside the port due to delay in loading and unloading at Gateway Terminals India."
