Microsoft attacks the Storm Worm

Storm Worm Chart“In total, malware has been removed by this month’s MSRT from 2,574,586 machines.”

Looks like some progress has been made recently in fighting back the worm. Awesome job guys. Microsoft aint all that bad. (wink)

But it seems we still have a ways to go:

Another antimalware researcher who has been tracking these recent attacks has presented us with data that shows we knocked out approximately one-fifth of “Storm’s” Denial of Service (DoS) capability on September 11th. Unfortunately, that data does not show a continued decrease since the first day. We know that immediately following the release of MSRT, the criminals behind the deployment of the “Storm” botnet immediately released a newer version to update their software. To compare, one day from the release of MSRT, we cleaned approximately 91,000 machines that had been infected with any of the number of Nuwar components. Thus, the 180,000+ additional machines that have been cleaned by MSRT since the first day are likely to be home user machines that were not notably incorporated into the daily operation of the “Storm” botnet. Machines that will be cleaned by MSRT in the subsequent days will be of similar nature.
