Summary: Worm. A program that is primarily replicating on networks or removable drives.
|WormAutorun||A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Worm's file once a user opens a drive's folder in Windows Explorer.|
|IRCBot||A bot can communicate with command and control servers via IRC channel.|
|MSNWorm||A worm can spread its copies through the MSN Messanger.|
|DNSBlocker||A program can block designated DNS servers for making it difficult for users to locate specific domains or web sites on the Internet.|
|UDPFlooder||This program can make a UDP flood. A UDP flood attack is a denial-of-service attack using the User Datagram Protocol (UDP). It can be initiated by sending a large number of UDP packets to random ports on a remote host.|
|SYNFlooder||This program can make a SYN flood. It is a form of denial-of-service attack in which an attacker sends a succession of SYN requests to a target's system in an attempt to consume enough server resources to make the system unresponsive to legitimate traffic.|
|Trojan-Proxy||This program can launch a proxy server (SOCKS4) on a designated TCP port.|
|USBInfector||A program can register a device notification with the help of RegisterDeviceNotification. So it is notified when a USB device is plugged and then the worm copies itself to the USB device plugged into the affected computer.|
