Wi-Fi users in India vulnerable to virus attack, warn analysts
Wi-Fi
users in the country are vulnerable to virus attack, warns an Indian
computer security analysis firm. According to the Indian Computer
Emergency Response Team (CERT-In), the virus attacks through Wi-Fi
could lead to crashing and even hacking of the secure networks. The
firm has discovered that the Wi-Fi Protected Setup (WPS) has a design
error, which increases risks of virus attacks and may allow attackers to
take unauthorised control of the affected system. The error can also
help attackers crack and stealthily enter into an encrypted and password
protected system.
“The virus is streaming in the Indian
Internet networks with a high severity. The combat mechanisms are being
deployed,” a computer security analyst with a government agency said.
“An unauthenticated, remote attacker within range of the wireless access
point could use the PIN (password) to gain unauthorised access to the
device to retrieve the password for the wireless network or change the
configuration of the device. Failed attempts to exploit the
vulnerability could lead to a denial of service condition,” the CERT-In said in its alert to Wi-Fi users.
The agency also pointed out its reports
that revealed several WPS devices do not feature any kind of lockout
policy for such attack attempts. Users in India mostly use the WPS
method to set up a wireless router for home network. The WPS procedure
requires a PIN that can be used during the setup phase. Issuing an
advisory to the Wi-Fi users, analysts of CERT-In said that users should
disable the external registrar feature of the WPS to protect their
device from virus attacks.
