Militants use ‘Calculator’ app; avoid surveillance

Jammu and Kashmir News

Srinagar: The terrorists infiltrating into Jammu and Kashmir, have come up with a new app called “calculator” which helps them to remain in touch with their handlers in PoK without being detected by the technical surveillance that has been embedded by the Army. This app has been found on smart phones of terrorists invading the state.


As the number of cross border movement is on the rise this year, the Army found that terrorists carried a smartphone with no messages stored in it.

The Army’s signal unit, which relies mainly on technical intercepts like usage of wireless and mobile phones by infiltrating terror groups to track them, is burning midnight oil along with the National Technical Research Organisation (NTRO) and other agencies to crack the mechanism used by terrorists. The technology was first used by a US-based company during hurricane Katrina so that the affected residents could remain in touch with each other.

During interrogation of some of the members of the terror group Lashkar-e-Toiba (LeT), it was disclosed that the terror outfit had modified it and created an application by the name “calculator” which could be downloaded on smartphones attached to the off-air network created specifically for them. The technology is based on the concept of “cognitive digital radio”, which enables users to turn their smartphones into peer-to-peer, off-grid communication tools.

The network generates its own signal through proprietary ad hoc networking protocols and automatically coordinates with other units within range which enables users to send and receive text messages, share their GPS locations on offline maps regardless of access to WiFi or cellular service.

The infiltrators had paired their phones with the radio sets along the border and were getting constant instructions about the route and terrain, making their task easy. With such technology readily available to the homicidal elements of the society, it becomes a matter of grave concern for the safety of the general population.
