Summary: Virus. A program that recursively replicates a possibly evolved copy of itself.

Dynamic Analysis

Payload

Behaviour Description
WormAutorunA 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 Virus's file once a user opens a drive's folder in Windows Explorer.
IRCBotA bot can communicate with command and control servers via IRC channel.
MSNWormA worm can spread its copies through the MSN Messanger.
DNSBlockerA program can block designated DNS servers for making it difficult for users to locate specific domains or web sites on the Internet.
UDPFlooderThis 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.
SYNFlooderThis 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-ProxyThis program can launch a proxy server (SOCKS4) on a designated TCP port.
USBInfectorA 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.

Propagation

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 Virus's file once a user opens a drive's folder in Windows Explorer.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.A worm can spread its copies through the MSN Messanger.
