NEWS The US-based Computer Emergency Response Team (Cert) has advised system administrators to check any holes in Unix systems running Secure Shell (SSH) are plugged before Christmas because of an expected increase in hacker activity. Cert said although vulnerabilities in several implementations of the SSH protocol have been discovered before and patches issued, the team believes many system administrators might have overlooked some of the vulnerabilities. A statement from Cert said: "We are seeing a high amount of scanning for SSH daemons (programs which handle requests), and we are receiving reports of exploitation." SSH is widely used for secure remote terminal connections and file transfers between a client and a server running Unix. SSH tools are available for free by the OpenBSD project and sold by vendors such as SSH Communications Security and F-Secure.
