D-Link adds CAPTCHA anti-trojan security to routersMay 12, 2009 – 5:26 AM
D-Link have announced new CAPTCHA security for selected models in their router range, promising more resilience against DNS-altering malware and spyware. The new firmware – which is also available to upgrade on existing models – adds the familiar distorted letters and numbers to common router settings pages.
By changing the DNS settings in a home or office router, users’ traffic can be diverted through a security-impaired network where login, credit card and internet banking details are harvested. Even if the router is password protected, entering that password from a malware-infected PC can then give the trojan access; the CAPTCHA prevents that.
D-Link router models that now feature CAPTCHA include the DIR-615, DIR-625, DIR-628, DIR-655, DIR-825, DIR-855, DIR-685 and DGL-4500. The updated firmware is available at support.dlink.com.
