There is some evidence (from NANOG) that something much more beautifully subtle and ironic is happening in a similar vein: 1) Take standard-issue Windows 2000 or XP host with a default configuration (to wit, 'append domain when searching for host' - unline the BIND resolver, this is tried *before* the straight name). 2) Set the domain name to 'thiscompanydoesnotexist.com' or some similar value (must be .com/.net, and not actually exist). 3) Do a lookup on 'windowsupdate.com' - it tries to lookup 'windowsupdate.com.thiscompanydoesnotexist.com' (using the example domain above). Returns VeriSign's A record. And now, the payoff... 4) Add MS Blaster (which does step 3, above, then fires off DoS traffic at it). Microsoft, VeriSign, and MS Blaster - three great tastes that go great together! (Well, okay, three really nasty tastes that cause a beautifully elegant reprisal against stupidity.) -- Joel Baker <[EMAIL PROTECTED]> ,''`. Debian GNU NetBSD/i386 porter : :' : `. `' `-
