New Delhi:
Websites of key Indian government organisations, including an adviser to the Prime Minister and the Defence Research and Development Organisation (DRDO), reportedly came under cyber attacks on Wednesday night, leading to their shutdown for a while, government sources said on Thursday.
The government sources said some "suspicious and unwanted" activity was observed on these websites, maintained by the National Informatics Centre (NIC), following which these were shut down for a couple of hours.
"After checking the websites, these were restored," a source said, adding that the information contained by these websites is already in the public domain.
"There are no secrets on these websites," they stressed.
Among the sites that came under the attack were those of the prime minister's adviser on public information, infrastructure and innovations - http://iii.gov.in, and Recruitment and Assessment Centre (RAC) of the DRDO - www.rac.gov.in.
Sam Pitroda is the Prime Minister's adviser on public information, infrastructure and innovations, while RAC takes care of the process of scientists recruitment for the DRDO.
The cyber attackers group, said to be 'SanFour25', also targeted five more Indian websites and defaced them.
