Information about W32/Rbot-YV can be found at: http://www.sophos.com/virusinfo/analyses/w32rbotyv.html W32/Rbot-YV is a Windows network worm which attempts to spread via network shares. The worm contains backdoor functions that allows unauthorised remote access to the infected computer via IRC channels while running in the background. The worm spreads to network shares with weak passwords. When run W32/Rbot-YV moves itself to the Windows System folder as winsys32.exe. The worm then creates the following registry entries so as to run itself on computer logon: HKCU\Software\Microsoft\Windows\CurrentVersion\Run Configuration Loader Service winsys32.exe HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices Configuration Loader Service winsys32.exe HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run Configuration Loader Service winsys32.exe Once installed, W32/Rbot-YV will attempt to participate in denial of service (DoS) attacks, download and run files from the Internet and steal CD keys when instructed to do so by a remote attacker. The worm may also try to exploit backdoors and vulnerabilites used by the MyDoom family of worms.
