Viggly Vorm

We probably all know about the worm that ate the Internet now. The technical details are simple enough for even me to grasp. It's a worm which copies itself into the memory of unprotected SQL servers and proceeds to create enough Internet traffic that it swamps the network.

So far, so good. The thing I fail to comprehend is, if there has been a patch available for this vulnerability for the last six months, why have so few people got round to installing it? I realise that the majority of the people who read this are likely to around 3000% more tecchie than me, so can you explain this to me? It seems self-evident that these sorts of security patches should be a first priority for anybody operating a server.

But what do I know? I'm only a hack.
