More Information

W32/Rbot-LV is a worm which attempts to spread to remote network shares. It also contains backdoor Trojan functionality, allowing unauthorized remote access to the infected computer via IRC channels while running in the background as a service process.

W32/Rbot-LV spreads to network shares with weak passwords as a result of the backdoor Trojan element receiving the appropriate command from a remote user. The worm may also spread through IRC channels by using DCC.

W32/Rbot-LV moves itself to the Windows system folder as COMMAND32.EXE and creates entries in the registry at the following locations in an attempt to run on Windows logon:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
candy = command32.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
candy = command32.exe

W32/Rbot-LV may also create the following registry entry:

HKCU\Software\Microsoft\OLE\
candy = "command32.exe"

W32/Rbot-LV may also log keypresses, steal Windows passwords, participate in DDOS attacks and steal keys for certain software products.
