The National Informatics Centre, which builds and manages nearly all government websites, and the Centre for Development of Advanced Computing, a premier research institute that has built supercomputers, have actively installed patches to immunise their Windows systems, Sundararajan said, according to the agency report. "We have not got any reports of widespread infection of the ransomware", she said. It exploits a flaw in Microsoft's Remote Desktop Protocol in Windows XP and Windows 2003 operating systems.
