So much has been documented on the IST over the years, that mentioning them now, just doesn't give the same sense of "wow" as it used to - we're so used to the crap they get up to now, that it just doesn't surprise us anymore.

The latest I've come across is certainly nothing new, Blackhat SEO has been going on for years, but is interesting in that the domain it points to (fi97.net) - doesn't actually seem to resolve (kinda defeats the object there guys). OpenDNS, even after refreshing the cache, is showing 3 servers returning "Did not resolve" and the other 3 returning a "SERVFAIL" error.

There's no denying that the IST are involved in this, as the IP PTR kinda gives it away. However, I do find their code a little interesting (though not as interesting as those that use obfuscation, as it takes the challenge away).
