Dynamic Analysis

Payload

Behaviour	Description
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.

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 Worm'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.

Removals

Remove it with Ad-Aware

1. Click (here) to download and install Ad-Aware Free Antivirus.
2. Update the definition files.
3. Run a full scan of your computer.

Manual removal*

1. Scan a system with an anti-rootkit tool.
   
2. Terminate malicious process(es) (How to End a Process With the Task Manager):

   mspaint.exe:3040
   1.exe:3180
   notepad.exe:2792
   charmap.exe:3928
   %original file name%.exe:2656
   %original file name%.exe:2744

   wipmania.com:764
   wipmania.com:1376
   2.exe:3624
   2.exe:3256
   2.exe:3344

3. Delete the original Worm file.
   
4. Delete or disinfect the following files created/modified by the Worm:

   %Documents and Settings%\%current user%\Application Data\c731200 (1281 bytes)
   

5. Delete the following value(s) in the autorun key (How to Work with System Registry):

   [HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
   "Gpwiwo" = "%Documents and Settings%\%current user%\Application Data\Identities\Gpwiwo.exe"
   
   [HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
   "Cqwiwk" = "%Documents and Settings%\%current user%\Application Data\Microsoft\Cqwiwk.exe"
   
   [HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
   "enowpea4" = "C:\RECYCLER\S-1-5-21-0243556031-888888379-781863308-5181719\enowpea40.exe"
   
   [HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
   "Screen Saver Pro 3.1" = "%Documents and Settings%\%current user%\Application Data\ScreenSaverPro.scr"

6. Remove the references to the Worm by modifying the following registry value(s) (How to Work with System Registry):

   [HKCU\Software\Microsoft\Windows NT\CurrentVersion\Winlogon]
   "Shell" = "explorer.exe,C:\RECYCLER\S-1-5-21-0243556031-888888379-781863308-5181719\enowpea40.exe"

7. Clean the Temporary Internet Files folder, which may contain infected files (How to clean Temporary Internet Files folder).
   
8. Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
   
9. Reboot the computer.
   

*Manual removal may cause unexpected system behaviour and should be performed at your own risk.
