Fearing that national security could be compromised, the Army has asked its personnel not to use social media like Facebook and WeChat which may have servers abroad.
The army is worried that activity on the social media could lead to identification of the army officers and others and their location, sources said.
Chatting sites such as Facebook and Wechat have become quite popular in India and are among the top downloaded applications on smart phones and tablets.
In the past, there have been cases where army officers have been honey-trapped by suspected agents working for Pakistan's ISI and they have faced strict action from the force.
More than two Navy officers were also tried and punished by the maritime force after they were indicted for using Facebook accounts and disclosing the position of their respective ships.
Security and intelligence agencies have been probing the origins of such web-based chatting platforms with fears that their servers could be based in China having links with the People Liberation Army.
