Operations at a terminal at India's busiest container port have been stalled by the malicious software that has crippled computers globally, an official said.
"While the DP World and JNPT terminals are operational, the Gateway Terminals India operated by APM is completely shut down", said a JNPT official, requesting anonymity. "India is not much affected at this stage", IT Minister Ravi Shankar Prasad said. "They are trying to work manually".
However global cybersecurity firm Kaspersky Lab said they thought it was not a variant of Petya ransomware "but a new ransomware that has not been seen before".
The Copenhagen-based group says its APM Terminals have been "impacted in a number of ports", adding vessels with Maersk Line were "maneuverable, able to communicate and crews are safe".
The Maersk group too confirmed that its operations were hit by the cyber attack. DLA Piper said in a statement it was hit by a suspected malware attack and that it was "taking steps to remedy the issue".
The fresh wave of attack, which crippled some central banks and many large corporations in Europe, came weeks after a similar incident - Wannacry - that had affected systems of many companies.
Several multinational companies said they were targeted, including USA pharmaceutical giant Merck, Russian state oil giant Rosneft, British advertising giant WPP and the French industrial group Saint-Gobain. Given that it will take a hours to get the terminal running, the Trust has freed up additional parking space for cargo containers.
The IT team of AP Moller-Maersk together with the IT companies in the country are working to restore the sytems and resume cargo operations, it said.
Kremlin-controlled Rosneft, Russia's largest crude producer, said in a statement that it avoided "serious consequences" from the "hacker attack" by switching to "a backup system for managing production processes".
The Ministry and JNPT are taking steps to ensure minimum disturbance to trade, transporters and more importantly local citizens.
