Computer systems of a private hospital in Navi Mumbai have come under a malware attack, with attackers seeking ransom in Bitcoins, police today said. The cyber attack on the computer systems of Mahatma Gandhi Mission Hospital came to light on July 15, police said.

Hospital administrators found the systems locked, with an encrypted message by unidentified attackers demanding ransom in Bitcoins to unlock it, said Tushar Doshi, Deputy Commissioner of Police (Crime).
