Chapter 7: Network worms
On July 16, 2001 Code Red started propagating on Microsoft Windows systems with ISS installed. It exploited IIS-enabled systems susceptible to the vulnerability described in CERT advisory CA-2001-13 Buffer Overflow In IIS Indexing Service DLL. Other systems not vulnerable to this exploit. Reports indicate that two variants of the "Code Red" affected more than 250,000 hosts.
If you want to watch the spread of the "Code Red" worm, here are the URL's you need. The bottom line is that it is definitely out there and spreading exponentially, it may be capable of matching the extent of the last outbreak, a new version is capable of spreading much more quickly, the exponential growth may be leveling off, but it will be a week before anybody knows anything for sure, and so long as there remain large numbers of unfixed servers, there is nothing to prevent any of endless thousands of individuals from releasing an even more sophisticated worm that fixes the remaining obvious mistakes in the one that's circulating now. That said, there has been a whole lot of uninformed panic caused by (among other things) inaccurate reports that all Windows NT and Windows 2000 machines are at risk of infection. Only machines running Microsoft's IIS server program are at risk, and only some of them, and only if they haven't been patched and I suppose power cycled. At the same time, everyone is at risk of a bad day if either the worm's probes or its later DDOS attacks clog up the net or crash routers.
