Pakistani spies have been calling up Rashtrapati Bhawan, the ministry of defence, the army headquarters and other highly sensitive offices using call spoofing software in an effort to get information, say intelligence sources.
Sources say in the past few months, agents of Pakistani spy agency ISI tried to gather information from Rashtrapati Bhawan and other highly sensitive offices and that there was a need to remain alert when officials in sensitive organisations spoke to unknown persons. The IB suspects in some instance information may have been passed on to the suspected agents.
Intelligence officials say ISI operatives are using call spoofing software to make the calls. These numbers start as 2301 or 2309 to indicate the calls are from some government office at Raisina Hill.
On February 21, immediately after the Dilsukhnagar blasts in Hyderabad, a person claiming to be Major Ajay Sharma from ‘MI-3’ had contacted the NSG headquarters.
The calls were further directed to the NSG office in Hyderabad. During the call, the officer on duty had given away some details about the deployment of the NSG team from Hyderabad at the blast site. Sources say an ISI official by the name of Mohammad Tasleem was behind the incident.
