The advisory has been sent to Defence, External Affairs, Civil Aviation, Finance, Power and Telecom Ministries by the Home Ministry asking them to ensure that all computers carrying classified information were put on "intranet" (an internal communication software) and no official accesses internal on those machines.
The security advisory said that the Pakistani intelligence agencies were particularly targeting headquarters of sensitive security establishments of armed forces, paramilitary forces in order to obtain sensitive information by be-fooling government officials, official sources said.
The advisory said since the international gateways are being used for such purposes, it has been impossible to do a back-tracking exercise on these numbers and they leave very little or no electronic trace behind them.
