W32/Codbot-I is a network worm and IRC backdoor Trojan.
W32/Codbot-I can spread to remote network shares protected by weak passwords and computers vulnerable to common exploits, including the RPC-DCOM (MS04-012) and Webdav (MS03-007) vulnerabilities. See:

W32/Codbot-I can be controlled by a remote attacker via the IRC network. The attacker can issue commands to download and run further malicious code, steal passwords and system information and sniff packets from the local network.
