Summary:

Banker. Steals data relating to online banking systems, e-payment systems and credit card systems.
Backdoor. Malware that enables a remote control of victim's machine.
WormAutorun. A worm spreads via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Backdoor's file once a user opens a drive's folder in Windows Explorer.
IRCBot. A bot communicates with command and control servers via IRC channel.
MSNWorm. A worm spreads its copies through the MSN Messanger.
DNSBlocker. A program blocks 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 registers 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.

Network activity (URLs)

A bot communicates with command and control servers via IRC channel.
This program can launch a proxy server (SOCKS4) on a designated TCP port.
A program blocks designated DNS servers for making it difficult for users to locate specific domains or web sites on the Internet.
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.
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.

Propagation

A worm spreads via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Backdoor's file once a user opens a drive's folder in Windows Explorer.
A program registers 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.
A worm spreads its copies through the MSN Messanger.
