Network protection firm Internet Security Systems missed an insecure spot in its sweeps, but a group of online vandals didn't. On Tuesday, the firm acknowledged that a group of Web defacers known as the Unix Security Guard, or USG, had managed to digitally tag a single page on its Web site, replacing it with an antiwar message that dismissed the leaders of the United States, the United Kingdom and Israel.
The Atlanta-based security company said the intrusion was minimal. "ISS has confirmed that one Web page was modified on a noncritical server on an isolated network that provides free copies of BlackICE PC Protection to college students," ISS said in a statement. "No further attacks have occurred."
