Information about W32/Rbot-YN can be found at: http://www.sophos.com/virusinfo/analyses/w32rbotyn.html W32/Rbot-YN is a network worm with backdoor functionality for the Windows platform. W32/Rbot-YN may spread to remote network shares protected by weak passwords and computers vulnerable to common exploits. The worm also opens up a backdoor, allowing unauthorised remote access to infected computers via the IRC network, while running in the background as a service process. The worm exploits the following vulnerabilities: RPC-DCOM (MS04-012) and LSASS (MS04-011). W32/Rbot-YN can receive commands from a remote intruder to delete network shares, log keypresses, participate in DDoS attacks, scan other computers for vulnerabilities, steal passwords, steal registration keys for computer games, create administrator accounts, terminate firewall and anti-virus processes and capture video from webcameras attached to the computer. W32/Rbot-YN copies itself to the Windows system folder as "msnshed.exe" and creates the following registry entries in order to run automatically on computer logon: HKLM\Software\Microsoft\Windows\CurrentVersion\Run\ msnshed msnshed.exe HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\ msnshed msnshed.exe HKCU\Software\Microsoft\Windows\OLE\ msnshed msnshed.exe This IDE file also includes detection for: Troj/Banker-BO http://www.sophos.com/virusinfo/analyses/trojbankerbo.html Troj/Haxdoor-AE http://www.sophos.com/virusinfo/analyses/trojhaxdoorae.html Dial/XXXDial-G http://www.sophos.com/virusinfo/analyses/dialxxxdialg.html Troj/Multidr-CO http://www.sophos.com/virusinfo/analyses/trojmultidrco.html Troj/LdPinch-AR http://www.sophos.com/virusinfo/analyses/trojldpinchar.html W32/Rbot-YZ http://www.sophos.com/virusinfo/analyses/w32rbotyz.html Troj/IPCScan-B http://www.sophos.com/virusinfo/analyses/trojipcscanb.html Download the IDE file from: http://www.sophos.com/downloads/ide/rbot-yn.ide Download all the IDE files available for the current version of Sophos Anti-Virus in a single compressed file.
