New Delhi, Mach 13: Chinese hackers have breached the systems of Defence Research and Development Organisation (DRDO) leading to the leak of thousands of top secret files related to Cabinet Committee on Security, which have been detected to have been uploaded on a server in Guangdong, the Mumbai newspaper DNA reported.
The report says this is the biggest security breach in the Indian defence establishment.
The breach was detected in the first week of this month when officials from India's technical itelligence wing, NTRO (National Technical Research Organisation), working with private Indian cyber security experts cracked open a file called "army cyber policy".
The file was found attacked to hacked email accounts of senior DRDO officials that quickly spread through the system in a matter of seconds, says the DNA report.
As Indian security experts began to track its origin, they discovered, for the first time, that all the sensitive files stolen from the infected systems were beingu ploaded on a server in Guangdong province of China.
So far, Indian intelligence had never been able to pinpoint a hacking attack with such accuracy.
Indian cyber security experts discovered thousands of top secret CCS files, and other documents related to surface-to-air missile and radar programmes from DRDL, a DRDO lab based in Hyderabad, among many other establishments.
Even the e-tickets of DRDO scientists who had travelled to Delhi in February were found on the server.
Intelligence officials also discovered documents of deals struck between DRDO and Bharat Dyamics Ltd, a defence PSU which makes strategic missiles and components.
Other recovered files related to price negotiations with MBDA, a French missile manufacturing company.
