The Anti-Malware Engineering Team, the team that builds the core antivirus, antispyware, anti-rootkit, and related technology used across a number of Microsoft products and technologies, posted on their blog recent "Storm" worm statistics based on the latest release of the Malicious Software Removal Tool (MSRT) developed and updated by Microsoft’s Malware Protection Center (MMPC). According to the Anti-Malware Engineering Team, as of 2PM on Tuesday, PDT, 18 September 2007, "the Renos family of malware has been removed from 668,362 distinct machines. The Zlob family has been removed from 664,258 machines. And the Nuwar family has been removed from 274,372 machines. In total, malware has been removed by this month’s MSRT from 2,574,586 machines." It has also been reported that another anti-malware researcher who has been tracking these recent attacks presented data that shows that the team knocked out approximately one-fifth of "Storm's" Denial of Service (DoS) capability on 11 September. No continued decrease was evident though since the first day which was presumably due to a newer version of the software that the criminals
behind the deployment of the "Storm" botnet has apparently immediately released.
