Whereas the original Code Red looked for 100 systems at a time to infect, the new strain looks for 300 at a time, unless the infected computer is running a Chinese-language version of Windows NT or Windows 2000, in which case it looks for 600 computers at a time, Maiffret said.

Code Red II is said to be more aggressive than the original worm because it installs a backdoor in servers that allows attackers to easily access the infected computer.
Code Red II is not a variant of the original Code Red, according to Security Focus, but rather a brand new worm that shares signatures of the original and imitates the method of attack.
Code Red was originally discovered in mid-July, shortly before it caused infected machines to launch a denial of service attack against the White House Web server.
