The Centre for Development of Advanced Computing in Hyderabad has been working on a technology to prevent compromise of mobile information of officials including those from the security establishment. Gadgets have become a source from where chances of espionage have increased. Mobile phones are most vulnerable and even set-top-boxes can be compromised. For mobiles, the government is developing a solution to prevent unauthorized access to communications of government officials, an official source said Cyber security researchers at Indian Infosec Consortium in November 2015 came up with a report saying phones of the Army personnel who had downloaded some mobile news application had been compromised by Pakistan-based hackers. The same was confirmed by a senior Army officer, clarifying that immediate action was taken and things were brought under control. The technology being developed is aimed at checking unauthorized access of microphone, SMS, storage and the like of a mobile phone by applications installed in it. "Most of the applications seek permission to access microphone, call record, SMS etc in a mobile phone. Users often fail to download a mobile application when they deny permitting to access microphone etc. The new technology will prevent such downloaded application on the phone from accessing security sensitive parts of a mobile phone," the official said further.
