The wireless fidelity (WiFi) Internet service of telecom companies has come under scanner and security agencies are likely to harden their stance on having a fool-proof mechanism in place at the earliest.

Coverage: Delhi Serial Blasts

The move comes close on the heels of militants of the Indian Mujahideen [Images] using the WiFi service to send an email around the same time of the serial blasts in Ahmedabad [Images] and Delhi [Images].

"We are seized of the matter and it would be taken up with appropriate authorities soon," a senior Home Ministry official said.

'We are victims of technology'

The official said the security agencies had pointed out that password protection should be made mandatory in every customer using the WiFi technology.

However, the recent hacking in its proxy server while sending the email ahead of the weekend blasts was a glaring example of how terrorists took advantage of unsecured networks, sources in the union Home Ministry said, adding that the Department of Telecom may not have placed in stringent measures.

While before the Ahmedabad blast, terrorists had used the unsecured WiFi system of an American national, Kenneth Haywood, in case of Delhi blasts, they used the unsecured network of a family in Chembur.
