- Storm Worm
- For information on the botnet composed of machines infected with this worm, see Storm botnet.
The Storm Worm (dubbed so by the Finnish company F-Secure) is a backdoor Trojan horse that affects computers using Microsoft operating systems, discovered on January 17, 2007. The worm is also known as:
- Small.dam or Trojan-Downloader.Win32.Small.dam (F-Secure)
- CME-711 (MITRE)
- W32/Nuwar@MM and Downloader-BAI (specific variant) (McAfee)
- Troj/Dorf and Mal/Dorf (Sophos)
- Trojan.Peacomm (Symantec)
- TROJ_SMALL.EDW (Trend Micro)
- Win32/Nuwar (ESET)
- Win32/Nuwar.N@MM!CME-711 (Windows Live OneCare)
- W32/Zhelatin (F-Secure and Kaspersky)
- Trojan.Peed, Trojan.Tibs (BitDefender)
The Storm Worm began infecting thousands of (mostly private) computers in Europe and the United States on Friday, January 19, 2007, using an e-mail message with a subject line about a recent weather disaster, "230 dead as storm batters Europe". During the weekend there were six subsequent waves of the attack. As of January 22, 2007, the Storm Worm accounted for 8% of all malware infections globally.
Ways of action

- 230 dead as storm batters Europe.
- Re: Your text
- Radical Muslim drinking enemies's blood.
- Chinese/Russian missile shot down Russian/Chinese satellite/aircraft

When an attachment is opened, the malware installs the wincom32 service, and injects a payload, passing on packets to destinations encoded within the malware itself. According to Symantec, it may also download and run the Trojan.Abwiz.F trojan, and the W32.Mixor.Q@mm worm. The Trojan piggybacks on the spam with names such as "postcard.exe" and "Flash Postcard.exe," with more changes from the original wave as the attack mutates. Some of the known names for the attachments include:
- Full Story.exe
- Read More.exe
Later, as F-Secure confirmed, the malware began spreading the subjects such as "Love birds" and "Touched by Love". These emails contain links to websites hosting some of the following files, which are confirmed to contain the virus:
According to Joe Stewart, director of malware research for SecureWorks, Storm remains amazingly resilient, in part because the Trojan horse it uses to infect systems changes its packing code every 10 minutes, and, once installed, the bot uses fast flux to change the IP addresses for its command and control servers.
The compromised machine becomes merged into a botnet. While most botnets are controlled through a central server, which if found can be taken down to destroy the botnet, the Storm Worm seeds a botnet that acts in a similar way to a peer-to-peer network, with no centralized control. Each compromised machine connects to a list of a subset of the entire botnet - around 30 to 35 other compromised machines, which act as hosts. While each of the infected hosts share lists of other infected hosts, no one machine has a full list of the entire botnet - each only has a subset, making it difficult to gauge the true extent of the zombie network. On 7 September 2007, estimates of the size of the Storm botnet ranged from 1 to 10 million computers. Researchers from the University of Mannheim and the Institut Eurecom have estimated concurrent online storm nodes to be between 5,000 and 40,000.
Another action the Storm Worm takes is to install the rootkit Win32.agent.dh. Symantec pointed out that flawed rootkit code voids some of the Storm Worm author's plans. Later variants, starting around July 2007, loaded the rootkit component by patching existing Windows drivers such as tcpip.sys and cdrom.sys with a stub of code that loads the rootkit driver module without requiring it to have an entry in the Windows driver list.
April Fool's Day
On April 1, 2008, a new storm worm was released onto the net, with April Fools-themed subject titles.
The list of antivirus companies that can detect the Storm Worm include Authentium, BitDefender, ClamAV, eSafe, Eset, F-Prot, F-Secure, Kaspersky, McAfee, Sophos, Symantec, Trend Micro, avast and Windows Live OneCare. The Storm Worm is constantly being updated by its authors to evade antivirus detection, so this does not imply that all the vendors listed above are able to detect all the Storm Worm variants. An intrusion detection system offers some protection from the rootkit, as it may warn that the Windows process "services.exe" is trying to access the Internet using ports 4000 or 7871. Windows 2000, Windows XP and presumably Windows Vista can be infected by all the Storm Worm variants, but Windows Server 2003 cannot, as the malware's author specifically excluded that edition of Windows from the code. Additionally, the decryption layer for some variants requires Windows API functions that are only available in Windows XP Service Pack 2 and later, effectively preventing infection on older versions of Windows.
Peter Gutmann sent an email noting that the Storm botnet comprises between 1 and 10 million PCs depending on whose estimates you believe. Although Dr. Gutmann makes a hardware resource comparison between the Storm botnet and distributed memory and distributed shared memory high performance computers at TOP500, exact performance matches were not his intention—rather a more general appreciation of the botnet's size compared to other massive computing resources. Consider for example the size of the Storm botnet compared to grid computing projects such as the World Community Grid.
An article in PCWorld  dated October 21, 2007 says that a network security analyst presented findings at the Toorcon hacker conference in San Diego on October 20, 2007, saying that Storm is down to about 20,000 active hosts or about one-tenth of its former size. However, this is being disputed by security researcher Bruce Schneier, who notes that the network is being partitioned in order to sell the parts off independently.
