More Information
W32/Rbot-LK is a network worm and backdoor Trojan for the Windows platform.
W32/Rbot-LK allows a malicious user remote access to an infected computer.
The worm copies itself to a file named wuamgrd.exe in the Windows system folder and creates the following registry entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Microsoft Update = wuamgrd.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Microsoft Update = wuamgrd.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Microsoft Update = wuamgrd.exe
The following registry entries are also modified:
HKLM\SOFTWARE\Microsoft\Ole\
EnableDCOM = "N"
HKLM\SYSTEM\CurrentControlSet\Control\Lsa\
restrictanonymous = dword:00000001
W32/Rbot-LK spreads using a variety of techniques including exploiting weak passwords on computers and SQL servers, exploiting operating system vulnerabilites (including DCOM-RPC, LSASS, WebDAV and UPNP) and using backdoors opened by other worms or Trojans.
W32/Rbot-LK can be controlled by a remote attacker over IRC channels. The backdoor component of W32/Rbot-LK can be used to:
start a proxy server
create screen/webcam captures
enable remote login (rlogin)
log keystrokes on the infected computer
filesystem manipulation
start/stop system services
take part in denial of service attacks (DoS)
send email
W32/Rbot-LK attempts to terminate the following processes:
i11r54n4.exe
irun4.exe
d3dupdate.exe
rate.exe
ssate.exe
winsys.exe
winupd.exe
SysMonXP.exe
bbeagle.exe
Penis32.exe
teekids.exe
MSBLAST.exe
mscvb32.exe
