Win32/Gaobot.ZI is a network worm that can spread across network connections by breaking weak passwords or by exploiting vulnerabilities described in multiple Microsoft Security Bulletins. The worm has backdoor capabilities, which allows attackers to control the infected computer using IRC channels. The worm also acts as a bot on the IRC network, coordinated through the IRC command, to launch massive distributed denial of service (DDoS) attacks and retrieve personal and system information.

Win32/Randex.AB.worm is a network worm that targets computers running certain versions of Microsoft Windows. The worm generates and scans IP addresses randomly to attempt to spread to writeable network shares that have weak passwords. The worm also has backdoor capabilities that allow attackers to control an infected computer through an IRC channel.

W32.Mimail.R@mm is a mass-mailing worm that targets certain versions of Microsoft Windows. The worm sends itself as an attachment to e-mail addresses that it finds on the infected computer. The worm is activated when the user opens the attachment. The worm also launches denial of service (DoS) attacks against certain Web sites.

W32.Mimail.T@mm is a mass-mailing worm that targets certain versions of Microsoft Windows. The worm sends itself as an attachment to e-mail addresses that it finds on the infected computer. The worm is activated when the user opens the attachment. The worm also launches denial of service (DoS) attacks against certain Web sites.
