"In terms of information lost or any specific thing, absolutely nothing has happened because it is already going to be shifted to our Isro site which is actually under construction," he told reporters in Thiruvananthapuram.
Kumar said that when a site is under construction, it is more vulnerable to hacking. "It is a case of Pharma hacking and not manual hacking," he said.
"So basically, what happens is that when some sites are under construction, they are more vulnerable. Many times advertisement people try to look for some credible sites through which they can put their information," he said.
The site, being managed by a Mumbai-based website provider, was in the process of being shifted to Isro server, he said.
An Isro official had earlier said in Bengaluru that the site appears to have not been hacked and that the problem might have occurred due to a purposeful attempt by someone to link the home page to another page.
The website was reportedly hacked yesterday and work to fix the problem was taken up by Antrix and it was blocked.
The official had said there was no cause of worry for the website does not contain sensitive data that could be detrimental for India's security.
Antrix is Isro's marketing arm for promotion and commercialisation of space products, technical consultancy services and transfer of technologies developed by Isro.
It provides space products and services to international customers worldwide. Its clientele includes EADS Astrium, Intelsat, Avanti Group, WorldSpace, Inmarsat and other space institutions in Europe, Middle East and South East Asia.
