INTERNATIONAL DOMAIN NAMES POSE A NEW SECURITY RISK

from an article here: http://www.sciam.com/2002/0602issue/0602scicit5.html
which i found on slashdot

----------------------------------
One example is a homograph of microsoft.com incorporating the Russian Cyrillic letters "c" and "o," which are almost indistinguishable from their Latin alphabet counterparts. The two students who registered it, Evgeniy Gabrilovich and Alex Gontmakher of the Technion-Israel Institute of Technology in Haifa did so to make a point: they suggest that a hacker could register such a name and take advantage of users' propensity to click on, rather than type in, Web links. These fake domain names could lead to a spoof site that invisibly captures bank account information or other sensitive details.
