"The current attack that's happened on the servers, here in the DRDO is possibly the biggest kind of cyber security breach that's happened in the history of cyber security jurisprudence in our country," said Duggal. The leak was detected in the first week of March as officials from India's technical intelligence wing, National Technical Research Organisation (NTRO), working with private Indian cyber security experts cracked open a file called 'army cyber policy'. The file had been attached to hacked email accounts of senior DRDO officials that quickly spread through the system in a matter of seconds.
