Like many Mac users, I've been busy this last week installing Apple's Open Transport Tuner 1.0. This patch blocks a potential denial of service attack that can be launched from Macintosh systems running Mac OS 9 and certain CPU configurations running Mac OS 8.6 - see Geoff Duncan's piece in this issue for details on the vulnerability and Apple's fix.
John Copeland, a professor at the Georgia Institute of Technology, identified this potential attack after detecting a port scan on his home network
In the beginning, the concept was simple: pay $10,000 to anyone who could bypass the security on a Macintosh Web server using only off-the-shelf software to protect the system (see TidBITS-303)
