Symantec offers free toolkit to counter CodeRed

Corporations worldwide infected by virus CodeRed Worm

MUMBAI -- August 6, 2001

WHAT:

CodeRed.v3 (CodeRed.C) was discovered on Aug 4, 2001. It has been called a variant of the original CodeRed because it uses the same "buffer overflow" exploit to propagate to other web servers. Symantec AntiVirus Research Center (SARC) received reports of a high number of IIS web servers being infected. Symantec is assessing CodeRed.v3 to be a high threat.

CHARACTERISTICS

The original CodeRed had a payload that will cause a denial of service attack on the white house web server. The variant called CodeRed.v3 has a different payload that allows the hacker to have full access of the web server remotely.

The CodeRed worm affects systems running Microsoft Index Server 2.0 or the Windows 2000 Indexing service. This worm only compromises computers running IIS 4.0 and IIS 5.0 on Windows NT and Window 2000 operating systems. CodeRed.v3 can establish more than 300 processes to search for other vulnerable servers to spread itself to.

Symantec is seeing a larger number of infections of CodeRed.v3 than the original version and this number is steadily increasing. This is because CodeRed.v3 has the ability to probe a larger number of IP addresses than the original version. This is causing an increase in the amount of activity on the Internet and a slowing down of the Internet.

RECOMMENDATIONS
/PROTECTION:

Symantec is offering a free tool called Symantec Security Check to determine if your computer is at risk. The tool is available free on the Symantec website www.symantec.com For organisations running Microsoft’s IIS server, it is strongly recommended to apply the latest Microsoft patch for protection from this worm. The patch can be found at: http://www.microsoft.com/technet/security/bulletin/MS01-033.asp

Norton AntiVirus is able to detect an infection on the web server by detecting the payload (torjan component) of this worm as Trojan.VirtualRoot.

Organisation that previously applied the patch are not at risk. Those that have not yet applied the patch will need to do so as soon as possible and if they have been attacked they will also need to clean up the Trojan that may be on their systems which will open their server to a possible hack attack even after they have applied the Microsoft patch.

We believe the new CodeRed.v3 worm was developed by a virus writing group from Europe called 29A. A more detailed write-up is available at http://www.symantec.com/avcenter/venc/data/codered.v3.html

Symantec is the only Internet security solutions provider to offer a comprehensive protection against the CodeRed attack.
