The hacking is suspected to have been carried out by Chinese hackers and there are fears that some sensitive information could have been compromised.
When asked about it, Defence Minister A K Antony said, "Intelligence agencies are investigating the matter at this stage and I do not want to say anything else."
The Minister was asked if the DRDO computer networks containing sensitive information were hacked and if information was compromised.
Commenting on the issue, DRDO spokesperson Ravi Gupta said, "as per our information, no computer or network of teh DRDO has been compromised."
Recently, the Navy had to take action against some of its officers in the Eastern Command after their networks were hacked as they did not follow the standard operating procedures.
