Lucent suffered a double hack attack yesterday when its XL.com website was defaced twice in a matter of hours.

A defacer calling himself Feltonspray got to the networking giant's XL.com site first, leaving the simple message: "Ops another site OWN3D by Feltonspray."

But only a few hours later zEr0, of the presumably Brazilian Quari Hack Force, took over the web server, which was running Netscape enterprise webserver on Irix.

zEr0 left a message in Portuguese which online translation service Babelfish can't make any sense of. "Que Zona Virou isso aqui Qualquer um que passa invade? zEr0 Quarai Hack Force," it read.

Lucent bought XL, or Excel as it is properly known, in 1999 for its open programming environment for switching platforms. The open platform technology allowed switches to bridge the gap between circuit and packet based networks.

But it looks like Lucent left more than the technology open in this case.
