The biggest-ever Pakistani ISI-backed spy network has been busted by the Military Intelligence of Jammu and Kashmir and the Crime Branch of Mumbai Police which was trying to collect the information of the Indian Defence in Ladakh, using illegal Voice over Internet Protocol (VoIP) exchange.
The Military Intelligence of Jammu and Kashmir and the Crime Branch of Mumbai Police have recovered three functional Chinese SIM boxes and one standby sim box along with 191 SIM cards, laptop, modem, antennas, batteries and connectors used for an illegal VoIP exchange in Mumbai.
According to sources, phone calls were coming from some international numbers on the mobile numbers of India. They asked for information about army in Jammu and Kashmir and their deployment on the border. On receiving the information, military intelligence came into action and sought cooperation from the police of other states.
All this was done through VOIP i.e. Voice over Internet Protocol. VoIP converted international voice calls originating from Pakistan into local GSM calls. The person who was called, felt that he was talking to someone in India. While in reality he was talking to an ISI agent sitting in Pakistan.
